Magnesium sulfate heptahydrate uses properties :
Magnesium sulfate heptahydrate (molecular formula MgSO4 7H2O), also known as sulfur bitter,
bitter salt, Epsom salt, Epsom salt, is white or colorless needle-like or oblique columnar crystal,
odorless, cool and slightly bitter, molecular weight: 246.47, The specific gravity is 1.68, easily
soluble in water, slightly soluble in ethanol and glycerol, and soluble in its own crystal water at 67.C.
Thermal decomposition, 70,80 ℃ is the loss of four molecules of crystal water. At 200°C, all crystal
water will be lost to anhydrous. In the air (drying), it is easy to be weathered into powder, and when
heated, the crystal water is gradually removed to become anhydrous magnesium sulfate. This product
does not contain any toxic impurities.
