Yesterday I went down to Science Essentials (in Brisbane) to buy some basic cobalt carbonate and a few beakers and was given various old chems for next to nothing. I ended up with:

- Basic cobalt carbonate 500g
- Magnesium oxide AR grade, some 200g
- Calcium gluconate anhydrous 500g
- Cobalt nitrate hexahydrate around 100g, plus 2 old bottles of cobalt nitrate that got wet.
- Sodium gluconate, about 20g
- Calcium carbonate around 200g
- Sodium metasilicate pentahydrate 500g

Have to read up on gluconates and the sodium metasilicate and see what to use them for.

Since you have so many metal salts, you can try the classic chemical garden experiment.
I'm curious if the rare earth salts would work or not.

Yes, they work. Only alkali metal silicates are soluble in water.

I second that, chemical garden experiment is awesome! yes any salt should work except for Group 1 metal salts...

I ordered some adipic acid. I want to try making some cubanes when I get a chance to do some chemistry.

Today I got the following

100g magnesium turnings
2000g sodium hydroxide
500g potassium hydroxide
100g menthol

As you can probably guess, I plan to make a lot of sodium metal and a bit of potassium through the alcohol catalyzed alkali metal production method. I'll have to make some dioxane at some point

I received the following chemicals:

- 300 grams of inositol for making rhodizonic acid and potassium rhodizonate
- 250 grams of benzoic anhydride for doing aromatic ester experiments
- 250 grams of copper sulfate, analytical reagent for very sensitive complex/coordination experiments
- 25 grams of 99.9% zinc arsenide, (no experiments planned yet, maybe make a tiny tiny little bit of AsH3 for Marsh test or something like that, need to think over the setup). Triple packed (little glass vial, wrapped in plastic bubble foam, put in second larger plastic jar).
- 50 grams of 99.9% zinc phosphide, for easily making small amounts of PH3. PH3 is quite interesting stuff. It is very toxic, but has no serious long-term effects and when handled with respect, its toxicity risk is comparable to the toxicity risk of H2S (it is more flammable though, but it does not numb your sense of smell at higher concentrations). Just work outside and with small amounts.

So, you also became interested with PH3 - it is very interesting what you will find.

100 grams of Rhodamin B were transfered from a ziploc bag to HDPE vial 10 days ago.
Red spots have started to appear in unexpected places. Darn that thing can fly !

10 grams Luminol
200 grams Fluorescein

Damn lol just how much stuff do you have? I keep seeing your posts around like "Just got 2 kg of Zr metal!" That's some dedication! But I prefer bigger amounts myself, so I get you... Is it more like a collection or are you just always working in the lab?

2 kg of Zr metal ? No, not that much :)
But I do have it in every form, several of them for display. Onyxmet and Chemcraft are great sources when you want beautiful or pure.

You're probably thinking about the 2 kg of Hg I'm supposed to get this weekend from someone who wants to get rid of it. Dont have it in my hands yet... Will definitely do a chloralkali cell just to tick that box and enjoy the sight until I get bored. All the products are easily obtainable otherwise.

I'll probably have a pretty picture to post with one of the dyes and a few other ones of something quite beautiful that grew in the reactor I use to dissolve silver.

Trick or treat !


Yay, just picked up this merury bottle from a friend who had been holding onto it for 43 years.

It is dirty as you can see on the bottle (used to be Merbromin, ah the irony!). Buuuut it's almost 2 kg and I'm not one to look into the mouth of a gift horse :)

Got myself 20Gr of PalladiumChloride reagent grade for 25$!!.
And 0.5 Kg of Mercury which I never owned before , magical stuff!
I was aware of its density but it is still the weirdest thing to hold such a tiny amount weighing that much.

Oh and 2Kg of analytical grade KOH for next to nothing.

Still waiting for my delivery of Vanadiumpentoxide which will be used as catalyst (contact process)

I was stunned and confused too, when I realized that it was this old man selling off his basement stock of chemicals it started to make sense , either he didnt know what he was selling or the last time he checked the palladium price was 1961.
Not sure but I am absolutely positive it is what is says on the original bottle.
It usually sells north of 115$ per gram!!

Has anyone ordered sodium metal (let's say 100 g) from Onxymet or Limac to the USA? Was it a pain in the ass dealing with customs? I know that sodium is one of the watchlist chemicals but I don't know what this means in terms of practically importing it. Their prices are so much lower than domestic suppliers...

100 grams of p-TsOH

I found that while sulfuric acid causes benzyl alcohol to polymerize, forming a tar and causing bad yields, p-TsOH (or using sulfuric acid + toluene as the dean-stark solvent) doesn't cause tar formation.
