MnSO3

Manganese(II) sulfite, with the chemical formula MnSO3, is an inorganic compound. It is the sulfite salt of manganese in the +2 oxidation state. Manganese(II) sulfite typically appears as a solid. Its solubility in water is generally low. When exposed to air, manganese(II) sulfite can oxidize to manganese(II) sulfate. It is not a commonly encountered compound in everyday applications. It can be synthesized through various chemical reactions, often involving manganese(II) salts and sulfite sources. For example, reacting manganese(II) chloride with sodium sulfite can produce manganese(II) sulfite as a precipitate. The compound has a crystalline structure. Like many inorganic sulfites, MnSO3 can decompose upon heating. Its stability and reactivity are characteristic of metal sulfites. Detailed thermodynamic data and spectroscopic properties are available in chemical literature for those interested in further study.
