Magnesium sulfate heptahydrate (molecular formula MgSO4.7H20), also known as sulfur bitter, bitter salt, epsom salt, epsom salt, is white or colorless needle-shaped or oblique columnar crystals, odorless, cool and slightly bitter, molecular weight: 246.47, The specific gravity is 1.68, easily soluble in water, slightly soluble in ethanol or glycerin, soluble in its own crystal water at 67.5 ℃. Thermal decomposition, 70/80 ℃ is to lose four molecules of crystal water. About 200 ℃ lost all crystal water into anhydrous. It is easily weathered into powder in the air (dry), and gradually loses crystal water when heated, and becomes anhydrous magnesium sulfate. This product does not contain any toxic substances. Soda magnesium sulfate is easier to weigh than anhydrous magnesium sulfate because it is not easy to decompose, which is convenient for quantitative control in industry.
