Drying agent for H2SO4?
I found this table of drying agents:
http://delloyd.50megs.com/moreinfo/drying.html
which is very useful. I was surprised to see CuSO4 can be used to dry acetic acid. I read on a thread on this forum that CuSO4 also dries nitric acid.
What about H2SO4. I've read about sulphuric acid being used as a drying agent but I've never heard of a compound for drying it.
