Manganese sulfate

Manganese Sulfate is an inorganic compound with the formula MnSO4. It is a pale pink deliquescent solid, which is a common laboratory and industrial chemical. Manganese sulfate is used primarily as a component in fertilizers and in other manganese compounds.

Chemical Properties

Manganese sulfate usually refers to the inorganic compound with the formula MnSO4(H2O). This pale pink deliquescent solid is a commercially significant manganese(II) salt. The compound forms a variety of hydrates: monohydrate (MnSO4•H2O), tetrahydrate (MnSO4•4H2O), and heptahydrate (MnSO4•7H2O). All forms are highly soluble in water, and therefore can be used in fertilizers and for hydroponic applications.

Production

Manganese sulfate is produced commercially by reducing manganese dioxide with sulfur dioxide. It can also be produced by dissolving manganese carbonate in sulfuric acid. Small scale production or laboratory synthesis of manganese sulfate can be achieved by heating manganese dioxide with sulfuric acid.

Applications

Manganese sulfate is a key component in various fertilizers and animal feeds, due to its high solubility in water. It is also used in the production of other manganese compounds, in the dyeing of textiles, and in the production of ceramics. In addition, it is used in health supplements for humans and animals, as manganese is an essential trace mineral.

Health and Safety

Exposure to manganese sulfate can cause irritation to the eyes, skin, and respiratory tract. Ingestion can lead to symptoms of manganese poisoning, such as headache, insomnia, and memory loss. Chronic exposure can lead to manganism, a neurological disorder that resembles Parkinson's disease.
