Glacial acetic acid & Calcium chloride
I made myself some glacial acetic acid and decided to make sure it was extra dry. After checking the web I decided to use some CaCl2 on it, however
when I added it some of it appeared (unless my eyes mistake me) to dissolve into the acid. After filtering out the remaining solids I still suspect
there's some CaCl2 in there. I was thinking of distilling it again to see if any CaCl2 would be left, if I did this am I right in thinking the acid
would come over first? Heating it like this wouldn't damage the acid in anyway either would it?

Glacial Acedic acid can be distilled. <a target="tab" href="http://delloyd.50megs.com/moreinfo/drying.html">This website that I always
use</a> says anhydrous copper sulfate is a good drying agent for GAA, or phorphorus pentoxide.

Why would the acid distill over first? Its boiling point is 119 degrees C.

CaCl<sub>2</sub> will act to prevent the water from distilling over at 100°C, won't it?

Colligative properties, yea.
@redox Now that the CaCl<sub>2</sub> has dissolved that's why distillation becomes necessarily, right HexJam?
