Nice iodine, but if you really like halogens you would have posted bromine

Nickel Sulfate crystals


These are some nickel sulfate crystals I made using Nimh batteries.

Copper sulfate that crystalized onto some nickels that i was trying to get nickel sulfate out of.

Also quick question: does nickel sulfate form co-crystals with copper sukfate?

Sad, you contaminated the crystals with dirt and oils on your hand...

i don't think that he's going to use them as seeds so i don't see the problem, and even if it was, a quick wash with acetone will remove any oils

Maybe redissolve in water to remove the nickel (coin) and recrystallize to make new crystals?

Yes, otherwise they start to lose water and get chalky. I used clear nail polish for mine.

I mostly made this on accident trying to recover a partially decomposed compound.
The compound was iron (iii) salicylate which acts strange under acidic and basic conditions. It seems to me the reactions between it, acids and bases is in equilibrium because it is all reversible. First, I added acid to give it a clear, yellow appearance and then base to turn it back to its original purple color. I added slightly to much base, however and a green solution and brownish precipitate formed, as well as some purple. Nothing had been mixed, so it formed 3 layers of different colors and was absolutely beautiful.

I've tried this before, from what I could tell - no. I've only ever seen one person report a two-transition metal sulfate co-crystal, but I've never been able to relocate that reference, so I'm dubious.

Iodine I made for my element collection: My first halogen!
I'm going strong with my collection, I am working on synthesizing boron this weekend.

Nice iodine, Abromination.

Before you do boron, make sure you ckeck out MrHomeScientist's videos on it. Both the old and the new. Old is good for procedure. New also mentions yield and purity issues (significant).

I've seen the new ones, I am pretty much doing exactly what he did except in an iron crucible and am using larger amounts of the oxide.
I'm not entirely sure I have seen the old one, I will go check that out.

Ha, well I am going to need a coffee grinder for my boric oxide. Its just too hard for my mortar and pestle. How would you describe the smell of diborane? Is it almost ozone like?

I'm not sure how pretty this is, but it is interesting IMO. This is a saturated solution of iron acetate. It had about 2" of solid in the bottom and about 2" of liquid above it and it was allowed to sit out for about 2 months. About 2 weeks in I noticed a little "puff" on the lip of the bottle and it steadily grew. I'm guessing that as the water evaporated the crystals grew up the side of the bottle and wicked the other solution. It grew faster and faster, I'm guessing b/c there was more surface area for the solution to evaporate.

This puff ball was very light, probably weighing about 7-8 grams, which is very little considering the size.

On another note I've found something odd when making the acetate. I used vinegar and allowed nails to sit in a bottle exposed to the air. Rust/acetate would form above the surface on the nails sticking out of the vinegar and it would be brown/orange. If I added some H2O2 I would get a nice pink/purpleish solution like a mix of maganese sulfate and KMnO4. Can anyone explain why I would get this color temporiarily as I've never seen any iron compounds those colors except for some very odd oxides (specially made pigments).

Well, yeah kind of. The primary reason for the formation of these crystals (also called raphides) is regulation of Ca2+ levels insinde plant tissues.
Some plants (e.g. Dieffenbachia) developed a secondary function and uses needle-like crystals of CaOx as a way to keep animals from eating them (they cause swelling when ingested).
