Drying reagents MgSO4 vs. Na2SO4

MgSO4 is more expansive, but as a drying reagent, it is much quicker and more complete than Na2SO4.
when a lot of water is present, MgSO4 generates heat, Na2SO4 does not.

Also MgSO4 is weakly acidic. You should not use it dry basic compounds such as alcohols and amines.
