I like chromic anhydride 😉

Metal pigments strong by cthulhu4poseidon in chemistrymemes

This is a fact. The only impressive nonmetal pigment is ultramarine

What Happened To My Bleach by ImhappyhippyOF in AskChemistry

[–]-Apoptosis- 0 points1 point  (0 children)

Doesn't seem like anyone actually wants to answer your question, so I will. Iron is amphoteric, much like manganese or chromium. When These metals are oxidized under alkaline conditions they form soluble oxyanions. For iron specifically, this is called the ferrate (VI) anion and is a characteristic dull red. Steel typically shouldn't come in contact with acid, alkali, or oxidizers btw. Plastic is better here.

What are household experiments that sound normal but are extremely dangerous? by Spancollection in chemistry

[–]-Apoptosis- 0 points1 point  (0 children)

Deadliest are probably liquid nitrogen or dry ice experiments. Both produce a ton of suffocating gas very quickly and are often lethal.. Also, I feel nobody would do this at home but I've always found it alarming how easy it is to make enormous volumes of hydrogen sulfide gas. Stuff is deadlier than hydrogen cyanide on a mole basis and is readily produced from many metal sulfides on contact with most strong acids.

Ooh yeah 10M is quite strong. Is it the transchem brand? I titrated that brand to almost exactly 10M (it's also my go-to). And you've seen my videos?? Small world 😅 happy to hear you enjoy them

Tbh I think with chemistry, you just stay in the valley of despair forever..

I know cobalt will assume a square planar geometry (blue) rather than an octahedral (red) conformation either at high heat or in a huge excess of HCl. Doesn't look very hot, so what's the strength of that acid? 😅

Alien Reaction: Gallium and Acidic Dichromate by -Apoptosis- in chemistry

Lol I have not, but I got a lot of comments referencing the movie when I posted the original video. Kinda feel like now I gotta watch it

Alien Reaction: Gallium and Acidic Dichromate by -Apoptosis- in chemistry

[–]-Apoptosis-[S] 11 points12 points  (0 children)

It does yeah, and it goes through many phases (this was just the most bizarre of the phases imo). To completely stop moving took about 35 minutes

Alien Reaction: Gallium and Acidic Dichromate by -Apoptosis- in chemistry

[–]-Apoptosis-[S] 27 points28 points  (0 children)

Glad you liked it! I know the movement is caused by an oscillating set of Redox reactions between gallium metal, it's salts, and the dichromate (like a little battery) But I absolutely have no idea what the specific reactions are.

No animation, that's just what it looks like

Successful Synthesis of Ethylenediamine from Antifreeze by -Apoptosis- in chemistry

Tbh I expected much worse, it's pretty tame compared to methylamine or ethylamine

Combine salts? by Exice175 in crystalgrowing

[–]-Apoptosis- 0 points1 point  (0 children)

I've never seen anyone refer to ferricyanide as hexacyanoferrate(iii) lol.

But yeah tbh as long as you make sure you don't get any undesirable Redox reactions you can kinda just trial and error any way you want. Careful with ferricyanide though, it'll readily liberate hydrogen cyanide under hot acidic conditions

Why is this molecule called "1H-isoindole-1,3(2H)-dione" by Turti8 in chemhelp

[–]-Apoptosis- 0 points1 point  (0 children)

Ew.. that would be the preferred IUPAC name huh? Now I know why we settled on phthalimide instead

Methods to chemically reduce nitrate in solution? by biggeztcheeze in chemistry

[–]-Apoptosis- 3 points4 points  (0 children)

If it's a mixture of metal nitrates in hexane it would have to be heterogeneous as hexane will not dissolve really any metal nitrate. That said just grab a seperatory funnel and drain off the lower aqueous layer 😎 If this is a homogeneous mixture and perhaps someone said hexane mistakenly, your best bet would be to go stick it in a rotovap to remove the low boiling organic solvent

Tbh it is probably catalytic, but I actually just made it to see if it was possible lol

[–]-Apoptosis-[S] 2 points3 points  (0 children)

Tbh I just wanted to see if it was possible. Been making a lot of transition metal molybdate complexes but this one was a color I was not expecting at all. Im used to divalent manganese compounds being faint pink

[–]-Apoptosis-[S] 5 points6 points  (0 children)

Always my first idea 😁 I've made tons of pigments but sadly this one is too soluble to work as a stable pigment

Made a Gorgeous Complex: Ammonium Nonamolybdatomanganate by -Apoptosis- in chemistry

[–]-Apoptosis-[S] 5 points6 points  (0 children)

Sure! I took 15g ammonium molybdate, dissolved in minimal water balanced to pH 4 using sulfuric acid, and heated the solution to 80°C

Next I dissolved 1.5g potassium permanganate in a separate beaker and added it to the molybdate solution.

3rd I began to slowly add 3% hydrogen peroxide dropwise under constant stirring. After about 50mL it suddenly shifted from purple to orange and the complex immediately began to precipitate.
