Manganese (II) sulfate is the divalent manganese salt of sulfuric acid with the empirical formula MnSO ₄ . Manganese (II) sulphate forms pale pink monoclinic crystals when they contain water of crystallization and white crystals when they are free from water.

Occurrence

In nature, manganese (II) sulfate comes as the mineral Mallardit before (MnSO ₄ · 7 H ₂ O).

Manganese (II) sulfate tetrahydrate

Extraction and presentation

Manganese (II) sulfate can be prepared by dissolving manganese (II) carbonate in sulfuric acid.

properties

Manganese (II) sulfate is readily soluble in water , but insoluble in alcohols . It forms several hydrates (monohydrate, tetrahydrate, heptahydrate). The anhydrous substance is obtained by smoking most of the manganese compounds with sulfuric acid.

use

Manganese (II) sulfate is used as an additive in animal feed, in agriculture, in stuff printing, porcelain production , for disinfection , in dyeing and in wood stain .
