Manganese sulfate use
Manganese sulfate (chemical formula MnSO4, formula 151.00), its monohydrate is reddish orthorhombic crystal, relative density is 3.50, melting point is 700 ° C, soluble in water, insoluble in ethanol. It exists in the form of a plurality of hydrates. 
Manganese sulfate begins to decompose at 850 ° C. Due to the degree of heat, SO 3 , SO 2 or oxygen can be released, and the residue is manganese dioxide or trimanganese tetraoxide. When the crystalline hydrate of manganese sulfate is heated to 280 ° C, it can lose its own crystal water and become an anhydrate. 
Manganese sulfate is a trace element required for crops that synthesize fatty acids, so manganese sulfate can be applied as fertilizer to the soil and can increase production. Manganese sulfate is added to animal feed and has a fattening effect. Manganese sulfate is also a raw material and analytical reagent for the preparation of other manganese salts. Manganese sulfate is also used in industrial production such as electrolytic manganese, dyes, paper, and ceramics. 
Because of the deliquescence, the scope of application is limited. Manganese sulfate is non-flammable and irritating. Inhalation, ingestion or percutaneous absorption is harmful and irritating. Long-term inhalation of this product dust can cause chronic manganese poisoning. In the early stage, neurasthenia syndrome and neurological dysfunction are the main factors, and tremor paralysis syndrome occurs in the late stage. It is harmful to the environment and can cause pollution to water bodies.
