Description

Like many metal sulfates, manganese sulfate forms a variety of hydrates: monohydrate, tetrahydrate, pentahydrate, and heptahydrate, with the monohydrate being the most common. All these salts dissolve to give faintly pink solutions of the aquo complex [Mn(H2O)₆]²⁺. The pale pink color of Mn(II) salts is characteristic.
