Magnesium sulfate heptahydrate (molecular formula MgSO4·7H2O), also known as sulfur bitter, bitter salt, epsom salt, epsom salt, is a white or colorless needle-like or oblique columnar crystal, odorless, cool and slightly bitter, molecular weight: 246.47, specific gravity 1.68, soluble in water, slightly soluble in ethanol and glycerol, soluble in its own crystal water at 67.Chemicalbook 5 °C. Thermal decomposition, 70, 80 ° C is the crystalline water that loses four molecules. Month 200 ° C loses all the crystalline water into anhydrous. It is easy to weathered into powder in the air (dry), and the crystal water is gradually removed into anhydrous magnesium sulfate when heated, and this product does not contain any toxic impurities.
Because magnesium sulfate heptahydrate is not easily dissolved, it is easier to weigh than anhydrous magnesium sulfate, which is convenient for quantitative control in industry. It is mainly used in the manufacture of fertilizers, tanning, printing and dyeing, catalysts, papermaking, plastic chemicals, porcelain, pigments, matches, explosives and fireproof materials. It can be used for printing and dyeing thin cotton cloth and silk, as a weighting agent for cotton silk and a filler for kapok products; It is used as a Epsom salt in medicine.
