Description

It is a white monoclinic crystal or crystalline powder, odorless. It tastes bitter and salty. It’s also called anhydrous mirabilite, relative density is 2.68. The melting point is 884 centigrade. It’s soluble in water and glycerin, insoluble in ethanol. The aqueous solution is alkaline. When exposed to air, It’ll easily absorb moisture and turn into aqueous sodium sulfate. Fine anhydrous sodium sulfate with high purity is called Glauber salt.
