Introduction

Magnesium sulfate, also known as Epsom salt, sulphur bitter, chemical formula MgSO4, white crystal, contains many kinds of crystal water, among which magnesium sulfate heptahydrate MgSO4·7H2O is called Epsom salt; monohydrate magnesium sulfate MgSO4·H2O is called magnesia stone. Epsom salt is a colorless orthorhombic or monoclinic crystal. It loses 6 crystal waters at 150 °C to form magnesium sulfate; at 200 °C, it loses all water and becomes anhydrous. Magnesium sulfate is soluble in water, glycerol and ethanol. It is used as a fire retardant and dyeing auxiliaries in the textile industry, as a tanning agent and bleaching auxiliaries in the leather industry, and also used in industries such as explosives, papermaking, porcelain, fertilizers, etc., and in medical treatment Epsom salt is an antidote for barbiturates. , laxative, and for tissue anti-inflammatory. Magnesium sulfate can be obtained by using sulfuric acid to act on magnesium oxide, magnesium hydroxide or magnesium carbonate.
