Manganese(II) sulfate Manganese(II) sulfate Manganese(II) sulfate usually refers to the inorganic compound with the formula MnSO·HO. This pale pink deliquescent solid is a commercially significant manganese(II) salt. Approximately 260 thousand tonnes of manganese(II) sulfate were produced worldwide in 2005. It is the precursor to manganese metal and many other chemical compounds. Mn-deficient soil is remediated with this salt. Like many metal sulfates, manganese sulfate forms a variety of hydrates: monohydrate, tetrahydrate, pentahydrate, and heptahydrate. The monohydrate is most common. All of these salts dissolve to give faintly pink solutions of the aquo complex [Mn(HO)]. The pale pink colour of Mn(II) salts is
Manganese of manganese in air have dropped. Many racing competitions specifically ban manganese compounds in racing fuel for carts and minibikes. MMT contains 24.4–25.2% manganese. Elevated atmospheric manganese concentrations are strongly correlated with automobile traffic density. The Level of manganese emitted by MMT fuels has been found to be safe for the general population and vulnerable groups such as infants and the elderly by the EPA and European and Canadian environmental agencies. The tobacco plant readily absorbs and accumulates heavy metals such as manganese from the surrounding soil into its leaves. These are subsequently inhaled during tobacco smoking. While manganese is
