Why can't HCl acid be dried under silicagel or epsom salts? Is it becuase of azeotrope qualities of the water in the acid, which would mean that drying, or taking away some water out of the acid would just steal the acid in equal proportions as well? Cheese tried drying some HCl with a silica gel teabag and didn't really know what happened. It definatley adsobred some H2O/.

Yes, but is important to remember that when you produce HCl, you also produce heat i.e. you may carry some H2O along with it...
So, What I do is to have a condenser to allow H2O to flow back to the HCl/NaCl vessel...

So, I think that the question is: why can't silica gel or magnesium sulfate be added to hydrochloric acid to absorb the water and liberate HCl gas?
I think a good answer is: because HCl gas likes water even more than silica gel or anhydrous magnesium sulfate.

Rhodium's page has an excellent write-up about making dry HCl gas.
