stocking chemicals


SO im kinda just starting out and will be needing to obtain/make my chemical stock and safely store them.

I know there are lots of available chemicals like solvents and HCI and a few other acids (i saw the list in the sticky) but what about the other chemicals. what other chemicals should i be focusing on?

I think a good start for me would be making the chemicals i will eventually be using for other things. That way i will get practice with the processes and reactions that i can apply later on to my own experiments.

a short list maybe...

First of all, i should tell you this: my list of chemicals is extremely bias towards the first ten or so elements including a lot more there compounds than anything else because i am focusing element by element on each one. See my website for more info.

Usually whatever you need you can make. Or a lot of it. Personally i am pretty conservative home chemist. I don't do a lot of crazy reactions that are dangerous/risky. I am pretty basic. (but change may come with time), therefore i don't need a lot of exotic chemicals. Generally any chemical i want i can make or order at homesciencetools.com Great quanitys (small), prices are not great (on chemicals at least glassware is pretty good) fair selection and sell to anyone. 30mL 18mol sulfuric acid, no hazard fees no questions. Anyway, a few reactions are on my website so browse there if your looking for a place to start etc.

You might find the link below an interesting read. It is a page, I have written especially for the beginning home chemist. Suggestions are given for selecting chemicals to buy, and some other generic things. Hopefully it helps you.

The four absolute essentials that any home experimenter should strive to obtain are:

  • Hydrochloric acid (ideally > 30%).
  • Nitric acid (ideally > 60%).
  • Sulphuric Acid (ideally 98%).
  • Sodium hydroxide or potassium hydroxide.


Try to get these at any cost. (Nitric acid will be by far the most difficult.)

What to get next depends on what you want to do. One word of advice is to avoid the temptation to systematically collect every chemical you can. For example, if you have cobalt(II) chloride, there is relatively little need to buy cobalt(II) sulfate, cobalt(II) nitrate, cobalt(II) oxide or cobalt(II) carbonate. Instead, concentrate on obtaining a wide range of reagents.

i was reading that on the woelens site...
the HCI i have (muratic acid)
Sulphuric i should be able to get
Sodium hydroxide (lye) i can get
the nitric acid ill have to obtain some other way i guess.. or make it..

here is a nice list i found...

Acetaminophen generic Tylenol, grocery store/drugstore

Acetylsalicylic acid - aspirin, grocery store/drugstore (may require purification from binders and fillers for some purposes)

Acetic acid, dilute available as vinegar at grocery stores. Buy the cheapest white vinegar you can find; you don't want the flavorful organic traces of the more costly brands.

Acetic acid, glacial (concentrated) photo chemical

Acetone available as a solvent in paint stores/aisles and as an art supply.

Aluminum, foil - pretty obvious, at the grocery store. Be aware that most foil will not be pure aluminum but will contain small amounts of other elements such as silicon and iron.

Aluminum, powder - available as a filler for certain mixtures used with fiberglass; found at fiberglass suppliers (you may want to look online). The powder may come coated with some waxes or oils; these can generally be removed with cautious heating in an oven (BEWARE: aluminum powder is a flammable solid that burns with great heat once ignited) or rinsing with acetone.

Ammonium bifluoride, solution - hardware stores, as toilet bowl cleaner/rust stain remover

Ammonium hydroxide, dilute this is clear household ammonia. Beware, you don't want perfumed, colored, cloudy, or sudsy ammonia. Before buying, pick up the bottle and shake it. If it forms suds, you don't want it. I found plain, clear ammonium hydroxide at the local Thriftway as "Western Family Clear Ammonia."

Ammonium hydroxide, concentrated you can purchase a far stronger ammonia solution as a blueprint supply; search online (I've never seen a local blueprint supply store). This is not as concentrated as ammonia can get in water, but it is quite strong.

Ammonium nitrate available as prills at larger agricultural centers, in large sacks. You probably don't want to buy so much. Besides which the salespeople may be suspicious, since ammonium nitrate is easily converted to a blasting-grade explosive. More manageable amounts of ammonium nitrate (at much higher unit prices) can be found inside of instant chemical cold packs found in pharmacies/health aid aisles. Carefully cut open the outer plastic bag without puncturing the water bladder within, and store the pellets in an airtight container, since it is quite hygroscopic (absorbs moisture from the air).

Ammonium persulfate used to etch printed circuit boards; electronics store (catering to professionals; not Circuit City) or online

Ammonium phosphate available as a fertilizer, from agricultural/garden centers. I have actually seen this in chain stores too. Of course, you're once again stuck with a large container.

Ammonium sulfate another fertilizer that may not be too difficult to find.

Borax see sodium borate

Boric acid available from drugstore; I found mine at Bi-Mart.

Calcium chloride may be sold as a granular de-icing mixture at hardware stores; also sold as moisture absorbant in smaller containers.

Calcium carbonate chalk, marble, limestone - find these and you've found calcium carbonate.

Calcium hydroxide hardware store, garden supply center; may be called "lime," "hydrated lime," "slaked lime."

Calcium hypochlorite "shock treatment" chlorinating agent for pools. The purity varies considerably according to brand (examine the label). The purest materials may be hard to find outside of a dedicated pool/spa center.

Calcium nitrate a fertilizer - again, one that you're not likely to find at the local Target.

Calcium phosphate fertilizer

Calcium sulfate zounds, another fertilizer

Carbon, bulk charcoal. Get activated charcoal (expensive; drug stores) or natural lump charcoal (found near charcoal briquettes). Do not get charcoal briquettes. They are full of grit and binding compounds.

Carbon, rods welding supply shop or the inside of non-alkaline dry cell batteries (increasingly hard to find these nowadays)

Carbon dioxide, solid "dry ice," useful for low-temperature condensations and (rarely) as a chemical; often found at party supply outlets. I get mine from the nearest Baskin Robbins.

Camphor drugstore

Dextrose drugstore, health food store, even (some) well-stocked grocery stores

Diammonium phosphate - nutrient for wine fermentation. I found mine in the brewing/wine section of the local Thrifway. Hooray for the Northwest, land of DIY alcohol!

Copper sulfate root killer, available at hardware/general stores, usually in the plumbing section; also at some pharmacies.

Citric acid I found mine in the drugstore section of the local Thriftway. But it was expensive - $9.00 for 113 grams! I have since found that citric acid is sold in conjunction with home soap making (search online) for far less. It is also a photo chemical and used in brewing. Some grocery stores may stock it (one alternate name is "sour salt.")

Corn starch baking aisle at grocery store

Diammonium phosphate nutrient for wine fermentation. I found mine in the brewing/winemaking section of the local Thrifway. Hooray for the Northwest, land of DIY alcohol!

Dichloromethane, is found in chemical paint strippers (not the newer, less-toxic ones); it is generally mixed with another chemical or even multiple other chemicals. For some purposes it may be used as-is. For others it will need purification (not covered here). Look in paint store/aisle or hardware store and read the labels on the cans of paint remover.

Ethanol most famous of all alcohols. The stuff people like to drink. You can purchase denatured alcohol as a solvent and fuel in paint stores/aisles, and this is mainly ethanol, but such alcohol also contains a significant percentage of methanol, which may interfere in some reactions. 95% pure ethanol (the remainder is water) can be purchased at liquor stores under a variety of names; the most famous is probably Everclear. You will, of course, need the cooperation of someone 21 or older, and it is pretty expensive due to heavy taxes. It would also be a good idea to explain beforehand to parents why you need this.

Ferric (iron) chloride etchant for printed circuit boards; good electronics store or online (not Circuit City); I've seen it at Fry's Electronics.

Glycerin drugstore

Hexamethylenetetramine, solid fuel tables for portable stoves, barbecues, and campfires; found in sporting goods stores/aisles.

Hexamine see hexamethylenetetramine

Hydrochloric acid sold in paint stores/aisles, hardware stores, pool centers, agricultural centers, as "muriatic acid." As sold it is usually quite concentrated and will emit fumes of hydrogen chloride so it's not a great idea to use it indoors.

Hydrofluoric acid, dilute sold in grocery stores (cleaning aisle) and some hardware stores in brown plastic bottles as Whink rust stain remover. It is quite low concentration as sold; nonetheless, make sure you really do heed the safety warnings on the bottle.

Hydrogen peroxide, dilute grocery stores and drugstores

Hydrogen peroxide, less dilute sold in hardware stores, paint stores as part of "2 part wood bleach" kits or solutions. This hydrogen peroxide is generally between 30% and 40% concentration, as opposed to the 3% antiseptic solution from the drugstore. Thus it is not "concentrated," but it is far more potent than your garden-variety peroxide. Caution is definitely advised. You may be forced to buy 2 bottles of solution together in a kit when you really only want the peroxide bottle. The other bottle usually contains a solution of sodium hydroxide, sodium silicate, or a mixture of the two. Locally, at Portland Paint and Supply, I have found that "Daly's" brand wood bleaching solutions are sold unbundled, so I can just buy as much peroxide as I want without wasting money on the other solution. Solutions of 30% concentration, of very high purity (and no stabilizers! ) can be ordered from a variety of places online. It seems to be used as a sort of home remedy for everything under the sun, so you might check health food stores also. Solutions in this approximate strength range (not as good as wood bleach, but close) can also be found at pool/spa centers. Salon centers sell concentrations between 6% and 12% for bleaching hair, but it is weaker than all of the above sources and fairly expensive too.

Iodine, tincture you know as well as I do that this is found in a variety of drugstores or pharmacy areas. Can be purified to yield solid iodine or used as-is for some experiments. The related "Betadine," which comes in larger containers, might be substituted for some purposes. Very large containers of iodine tincture may be available at agricultural supply centers for animal use, but you risk suspicion, since this has recently been a preferred iodine source for drug labs.

Iron oxide pottery supply

Iron sulfate pottery supply, some agricultural centers

Isopropyl alcohol grocery store, drugstore; many places stock 99% purity now, so get it in preference to 70% or 91%.

Lithium carbonate - pottery glaze material

Lithium hypochlorite - rare chlorination chemical; likely impossible to find outside of a dedicated pool/spa center or online retailer.

Lead easily found as balls and wire in sporting goods store/department

Lead oxide pottery/ceramics; may be sold as "red lead" or "lead red."

Magnesium carbonate drugstore, perhaps some sporting goods stores

Magnesium sulfate "Epsom Salt(s)," often found at grocery store or drugstore; pottery supply; photo chemical; may also be sold as fertilizer.

Manganese dioxide pottery supply, fresh dry cell batteries (they need to be carefully disassembled and the black material removed).

Methanol this is the simplest alcohol of them all. Found as automotive gas-line antifreeze and water remover ("Heet" or similar), also available as photo chemical. If you just need a little bit and don't mind it being highly diluted with ethanol, denatured alcohol works.

Methylene chloride see dichloromethane

Nitrogenous matter, organic once in a while books (especially older ones) may call for or reference "nitrogenous organic matter." Basically, this means anything that came from living creatures that has a considerable amount of nitrogen (usually indicates proteins) in it. Blood meal, made from dried animal blood, generally fits the bill. It is available as a fertilizer at many garden/agricultural centers (including ordinary chain stores).

Oxalic acid available as fairly pure crystals in the form of wood bleach powder; found in hardware stores and paint stores/aisles; photo chemical.

Potassium bromide photo supply; for some reason this is much cheaper than the sodium salt.

Potassium carbonate also known as pearl ash, or potash; may be found in some pool/spa pH raising products; used in pottery/ceramics; photo chemical; clean hardwood ashes contain a considerable amount (but for most purposes would want purification).

Potassium chloride found as a sodium-free alternative to salt in materials for softening hard water (found at supermarket, hardware store); beware that it comes in big sacks. May also be found in big sacks as fertilizer. Found in more convenient sizes (and greater unit price) as salt substitute in grocery stores; check label to make sure there is no sodium contained; also photo chemical.

Potassium dichromate pottery, photo supply

Potassium hydroxide, solution the main (only?) ingredient in some drain openers; check the label to be sure it's not sodium-based or an acid opener; found at grocery stores, hardware stores.

Potassium iodide photo chemical, also sold (generally as pills, sometimes pure) as an emergency supply to help prevent the body from absorbing radioactive iodine in case of a nuclear disaster (look at stores, online or off, catering to survival gear).

Potassium nitrate found as fertilizer in large quantities, also as stump remover (found at garden centers) (this is my favorite compromise between price, size, and quality: $3.75 for a 5 pound box with some impurities); found at some drugstores (good purity, also expensive); may raise suspicions due to popularity of making pyrotechnics/smokebombs/black powder). Sold as a ceramic glaze component.

Potassium monopersulfate pool/spa non-chlorine shock treatment

Potassium permanganate sold for manually recharging water iron filters; I found mine at Sears in the plumbing section. I have checked around though, and not all Sears stores have it. So if a local Sears doesn't have it, order it from Sears' web site, or obtain it as a photo chemical (more expensive, though neither is exactly cheap). I believe that it was once found in drugstores, but I have never found it there. This may be another eye-raising chemical, since it can be used for fireworks/explosives and drugs.

Potassium phosphate fertilizer

Potassium sulfate fertilizer

Saltpeter see potassium nitrate

Silver nitrate photo supply or pottery; this is a very expensive chemical, so expensive that's almost worth buying some bullion silver and dissolving it in nitric acid yourself (pure silver is less than $6.00 an ounce and this chemical is more than $20.00/ounce).

Sodium bicarbonate "baking soda," grocery stores

Sodium bisulfate pH lowering chemical (solid) for pools

Sodium borate available as "laundry booster" for washing clothes; also used as flux for torch welding and ceramics

Sodium bromide sold in small packets for initial bromination of spas; also a photo chemical. Either way it's not cheap.

Sodium carbonate "washing soda" used to aid washing of clothes (grocery store, cleaning aisle); also sold as pH raising chemical for pools.

Sodium chloride ordinary table salt; don't get the iodized variety; you may want to recrystallize the salt to purify it of anti-caking agents (or try kosher salt if you can find it).

Sodium hydroxide grocery store or hardware store, sold as Red Devil Lye; small pellets in plastic bottle.

Sodium hypochlorite, solution liquid bleach, sold at grocery stores, or "liquid chlorine" (more concentrated) sold for chlorinating pools; both contain a good deal of sodium hydroxide although the bottle won't list it.

Sucrose this is ordinary white sugar

Sulfur may be available at drugstores as "flowers of sulfur"; sold for agricultural/garden use as dusting sulfur. The dusting sulfur may have up to 10% non-sulfur materials in it.

Sulfuric acid, concentrated when I first discovered this source I practically did a little jig because sulfuric acid is such a commonly used chemical, yet hard to obtain (or so I thought). There are a number of "professional strength" drain opener liquids that contain sulfuric acid. They are not generally found in grocery stores, but should be in any decent hardware store with the plumbing things. Some brands are more concentrated than others, and some contain dyes and extra additives to protect your pipes. I have been pleased with "Rooto" brand; it seems to be concentrated acid with minimal additives. Other brands that are supposedly good include "Crystal Power," "Instant Power," and "Liquid Fire." All of these are easily recognizable because they come in a plastic bottle enclosed in a heavy clear plastic sack. The concentration of these acids is good (not azeotropic, but greater than 90%) but they may contain substantial impurities, because they are made with waste industrial acid (or so I have heard). Oh, and they really do open up drains like a charm.

Sulfuric acid, dilute sulfuric acid of approximately 30% strength is available as replacement battery electrolyte for lead/acid cells. It is found at automotive stores. Acid of 48% strength is available as a photo chemical. Per unit of acid, these are both more expensive than the drain opener, but should also be higher purity (especially the photographic). I have seen 10% sold as pH reducer for pools, but it's hardly worth buying at that concentration.

Tartaric acid I have seen this sold as a wine making supply

Toluene sold as solvent in paint store/department

Trichloroethylene Sold as Sunnyside Carbo-Sol, available at paint stores; may also be sold under other brand names.

Trisodium phosphate hardware store, cleaning aisle of grocery store. TSP is harder to find nowadays because of marine pollution concerns, so check the label to make sure it's not a similarly-named substitute.

Turpentine paint store/aisle, crafts/hobbies; the turpentine that I have smells deliciously of evergreens, but I understand that there are some varieties which smell foul. The natural stuff is harder to find than synthetic substitutes.

Xylene sold as solvent in paint store/department

Neat I have all of those myself (and more) and the few that are missing are easy to make, it`s the Lithium Hypochlorite I really have missing, though I don`t have a use for it anyway :)
I have Li metal, but I value my glassware too much to dick about with the Hydroxide!

Nice List though!

You would do well to avoid totse textfiles, googling key phrases of the above list lead me to find that this list came from totse.
http://ww w.totse.com/en/bad_ideas/irresponsible_activities/163700.html
Although this list looks to be fine, you should be very wary of 'information' gotten off totse.

I have seen lithium hypochlorite...once...in the grocery store. At 37%(IIRC) and solid. I wish I had bought it when I saw it...I never saw it again. Could be nice for the haloform reaction due to not having an insoluble hydroxide like calcium, and much more concentrated than bleach. And lithium compounds could be made.

YT: I have had a solution of lithium hydroxide for a year in glass flask, and the flask seems fine. I got it from dissolving scrap lithium metal heavily covered in oxide and hydroxide in water.

going back to the OP question, I guess the Best answer is to stock that which you will Use!
anything else beyond that is a waste of Space and/or Money.

that at least would be the Logical Course of action.

yeah im gonna stock some acids and bases in dilute and strong. And start collecting other stuff.. i really like the idea of having a bunch of amber and cobalt bottles and containers with all my chemicals labeled and ready. I'll collect a bunch along the way im sure.

Well the reason is simple, I have decided to take a few courses in introductory chemistry at the local college, and plan to do my own experiments/research at home. Basically, i have found that chemistry is very interesting to me, especially organic chemistry. I don't expect to become some Nobel prize winning chemist or anything.

The reason (more specifically) for wanting to stock chemicals is so I can have them around if i need/want to use them in whatever experimentation I'm doing.

The reason for the bottles, is that they would be a great way for me to keep my lab areas and storage areas neat and organized while still maintaining a bit of aesthetic appeal.

I hope that answers your question. I wasn't sure exactly what you ment by "this".

Yes, Slimz' question is a very old one, but one that keeps popping up from time to time as new members join the forum. I say: "don't stock any chemicals - stock experiments!" What I mean here is draw up a list of experiments that you want to do and then let those experiments define what chemicals you buy.
In a few years you will have 200-300 chemicals just like the other long time members. :)

Slimz, I recommend getting The Illustrated Guide to Home Chemistry Experiments. It has a lot of basic chemistry experiments, and will most likely have every type of experiment to go along with that course you are taking. Good luck!
