Desiccator Bag for Drying Liquid Chemicals
I saw this video and this is a very efficient way to dry chemicals, i use calcium cloride and it works really well for hygroscopic chemicals like AN.
In this video also it is said that it is imposible to dry liquid chemicals, but i guess this is because of the use of KOH as a drying agent. What
about if we try other drying agents like calcium cloride for concentrating chemicals like H2SO4 or HNO3.

Yes, I wish there is something that can concentrate HNO3 by simply adding a salt that can pull the H2O out from the HNO3 and simply filter it instead
of doing a whole of distillation and such. Magnesium perchlorate is one of the strongest desiccants.. Not sure if it will work ? Any one ?
I am also eager to know the solubility of Phosphuric acid H3PO4 in nitric acid, so i can simply add P2O5 slowly, and freezing the solution/ filter (if
phosphoric acid is insoluble) However I am afraid it might be miscible with HNO3 since P2O5/HNO3 is often used nitrations reactions.

CaCl isn't very strongly hydroscopic, and would not work for H2SO4, in fact H2SO4 is used to desiccate CaCl somtimes.
Does this need to be in Energetic Materials?

So I was boiling sulfuric acid in aluminum soda can today and everything went well actually until it dissolved the inside and went purple? Manganese
sulfate ? Anyways what can I use to boil sulfuric acid? Stainless Steel ?

Tantalum and Titanium are resistant to boiling sulfuric acid.
Copper nickel alloy is also resistant but to a much lesser extent in a nonoxidizing environment but I would not trust that.

I made this to try and make anhydrous alcohol.
This video Nile Red I still can't believe that Epsom Salt is mostly water
I don't think my method, the toaster oven got hot enough to drive off the last of the h2o but I got alot of it out.
It worked to dry the alcohol but I did not get to 100%
I think if all the water was driven off the salt it would have been more 'sticky' grabbing away the water still holding on to the alcohol.
I only got the monohydrate.
