Storing Chemicals
ok, so there is this guy i used to know who has chems exposed to temperature fluctuations
it dips below freezing for about 12 hours
what he is most worried about is his HCl freezing, expanding, breaking the glass and dumping everywhere. It is lab grade HCl, it's about 3/4s full and
less than a gallon. Does anyone know the freezing point of HCl acid
he also has benzene, which he noticed was already frozen, does benzene expand like water?
also he has lots of ammonium salts that have had water leaked onto the cheap cardboard paper capsules that they came in
lots of anhydrous things have gotten wet. does a simple bake on low heat in the over or tucked under heating lamps do the trick on drying?
he made sure all his caps on the containers were cranked down as tight as he could make them, he will get electrical tape and put them on the threads
next visit

First of all, if
you're trying to do a "SWIM" thing, we don't do that here.

Depends on the concentration. What is
the concentration of it? No, water is very
unique in that regard. Very few compounds expand on freezing. Most do the opposite. | Quote: Originally posted by aYoungKing | | lots of anhydrous things have gotten wet. does a simple bake on low heat in the over or tucked under heating lamps do the trick on drying

Depends on what you're talking about. For some, that will work, but others will decompose when heated. What
sort of anhydrous "things" are you referring to?

35 - + % HCl
anhydrous things are
sodium sulfite
sodium carbonate
sodium bisulfite
sodium thiosulfate
NaOH, is already caked up inside the glass
KOH, already caked together inside the glass
magnesium
ferrous sulfide
calcium phosphate
lots of ammonium salts
mercuric chloride
sulfur, powder and lumps
iodine
many more things, will be posted after he visits the location

The HCl won't freeze, unless you live in Antarctica during the winter.
Let's give him the benefit of the doubt, before assuming he's a drug cook. The list of chemicals doesn't look very suspicious.
Still, unless he's actually talking about a friend, he should use "I".

@aYoungKing: Why use the "he" form? Your question is too specific and detailed for making me believe that you ask this question about someone else's
set of chemicals. These chemicals are yours and please be clear and honest about that. On sciencemadness we have had quite a few (wannabe) drugs cooks
who also were talking about "someone who is not me" and the use of this construct is frowned upon very much over here.
Your other post about replacement of phosphorus by some other chemical to make HI became suspicious because of the "not me" construct. If I simply
asked a question on how to make HI, then probably most people will not frown upon it (especially if you have a decent posting history already), but
combined with the "not me" construct and being a brand new member it certainly makes us think about drugs cookery.

The "someone I used to know" template is as illogical as it is suspicious. If you "used to know them" but don't currently, why are you asking very
precise questions on their behalf? If you're a drug cook, you'll likely be caught very quickly if this is how you operate.

@OP
Freezing point for 38% HCl is -26°C, and a little bit less for 35% conc. If you will want to dry anhydrous substances, you will need to look up on
wikipedia for boiling points or the decomposition temperature. You mustn't heat your compounds above boiling or decomposition point if you just want
to dry them.
