Magnesium sulfate heptahydrate (MgSO4 7H2O) appears as white or colorless needle-like or inclined columnar crystal, being odorless, cool and slightly bitter with a molecular weight of 246.47, specific gravity 1.68, being easily soluble in water and slightly soluble in ethanol and glycerol. In 67.5 °C, it is soluble in its own crystal water. It can be subject to thermal decomposition with loss of four molecules of crystal water molecules at 70, 80 °C. It will lose all the crystalline water at 200 °C to become anhydrous product. In the air (dry), it is easy to be weathered into powder with heating gradually removing the crystal water molecules to become anhydrous magnesium sulfate. This product does not contain any toxic impurities. Magnesium sulfate heptahydrate is difficult to dissolve and thus being easier to weigh than anhydrous magnesium sulphate for being convenient for quantitative control in industry. It is mainly used for the manufacture of fertilizer, tanning, printing and dyeing, catalyst, papermaking, plastic, porcelain, pigments, matches, explosives and fireproof materials. It can be used for printing fine cotton, silk, as the weighting agent of cotton yarn and the filler of kapok products; as Epsom salt of medicine.
