Manganese sulfate monohydrate

Manganese sulfate (chemical formula MnSO4, formula weight 151.00), whose monohydrate is the reddish orthorhombic crystal, the relative density is 3.50, the melting point is 700°C, and it is soluble in water and insoluble in ethanol. It exists in the form of various hydrates.

The manganese sulfate begins to decompose at 850°C, and it can release SO3, SO2 or oxygen depending on different heating degrees, and the residues include the manganese dioxide or manganese tetroxide. When the crystalline hydrate of manganese sulfate is heated to 280°C, it can lose its own crystalline water and become anhydrous.

The manganese sulfate is a trace element required for the crops to synthesize the fatty acids. Hence, the manganese sulfate can be applied to soil as the fertilizer, so as to increase the yield. The manganese sulfate can be added to the animal feed, to perform the effect of fattening. The manganese sulfate is also the raw material and analytical reagent for the preparation of other manganese salts. The manganese sulfate is also used in the industrial production, such as the electrolytic manganese, dyes, papermaking and ceramics.

Furthermore, there are various hydrates for the manganese sulfate, such as manganese sulfate monohydrate and manganese sulfate tetrahydrate.
