Physical Properties:

In their hydrated form, these salts have a pH of 6.0 (5.5 to 6.5) in solution. These magnesium sulfates are white crystalline solids. Their densities are: 2.66 g/cm3 (anhydrous); 2.445 g/cm3 (monohydrate); 1.68 g/cm3 (heptahydrate). Solubilities in water are: anhydrous＝ 26.9 g/100 ml (0°C); monohydrate＝ 25.5 g/100 ml (20°C); heptahydrate＝71 g/100 ml (20°C). Magnesium sulfate is found in nature in many salt deposits and mineral waters, occurring as hydrates or double salts. The heptahydrate or Epsom salt was discovered in 1695, found inthemineralwater at Epsom. Kieserite and epsomite are the two most important minerals. Other than these and the above hydrates, magnesium sulfate is also found in several other minerals, including langbeinite, leonite,vanthoffite,bloedite,kainite,polyhalite,
