A:
No. I believe that most salts will increase the density of alcohols etc. in which they dissolve. Generally salts only dissolve well in polar liquids, since in non-polar liquids the electrostatic cost of separating the opposite charges is high.
Slightly off-topic curiosity: Not all salts increase the volume of water. There's at least one, MgSO4, which slightly lowers the volume of water. So that makes it increase the density even more.
