Manganese Sulphate

Manganese(II) sulfate is the inorganic compound with the formula MnSO4. This colorless deliquescent solid is a commercially significant manganese(II) salt. Approximately 260M kg/y were produced worldwide in 2005.[1] It is the precursor to manganese metal and many chemical compounds. Mn-deficient soil is remediated with this salt.

Like many metal sulfates, manganese sulfate forms a variety of hydrates: mono hydrate, tetra hydrate, pentahydrate, heptahydrate. The mono hydrate is most common. All of these salts are faintly pink. The pale color of Mn(II) salts is characteristic of high-spin complexes with the d5 configuration.
