The most common is the heptahydrate MgSO 4 ·7H 2 O, [1] known as Epsom salt, which is a household chemical with many traditional uses, including bath ...
Molten FLiBe (2LiF·BeF 2). Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten salts are technically a class of ionic liquids.
4. Turn Up the Hot Water. There’s nothing quite like a long, hot shower for a little relaxation and stress relief, but think twice if you want to keep your skin in tip-top condition.
