Characteristic
Magnesium sulfate is an inorganic salt with the formula MgSO4(H2O)x where 0 ≤ x ≤ 7. It is often encountered as the heptahydrate sulphate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt.
Chemical formula:MgSO4
Molar mass:120.366 g/mol (anhydrous);138.38 g/mol (monohydrate);174.41 g/mol (trihydrate);210.44 g/mol (pentahydrate);228.46 g/mol (hexahydrate);246.47 g/mol (heptahydrate)
Appearance:white crystalline solid
Odor:odorless
Density:2.66 g/cm3 (anhydrous);2.445 g/cm3 (monohydrate);1.68 g/cm3 (heptahydrate);1.512 g/cm3 (11-hydrate)
Melting point:anhydrous decomposes at 1,124°C;monohydrate decomposes at 200°C;heptahydrate decomposes at 150°C;undecahydrate decomposes at 2°C
Solubility in water:anhydrous:26.9 g/100 mL (0 °C);35.1 g/100 mL (20 °C);50.2 g/100 mL (100 °C)
heptahydrate:113 g/100 mL (20 °C);Solubility 1.16 g/100 mL (18°C, ether)
slightly:soluble in alcohol, glycerol;insoluble in acetone
Magnetic susceptibility (χ):−50·10−6 cm3/mol
Refractive index (nD):1.523 (monohydrate);1.433 (heptahydrate)
Crystal structure:monoclinic (hydrate)
Application
Suitable for the preliminary drying of organic liquids, for example solvent extracts from reaction workups.
