Magnesium sulfite Magnesium sulfiteOther namesMagnesium sulphiteIdentifiers CAS number 7757-88-2 ChemSpider 2282946 EC number 231-825-6 Properties Molecular formula MgSO3 (anhydrous); MgSO3·6H2O Molar mass 104.368200 g/mol; 212.4599 g/mol (with water) Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa) Infobox references Magnesium sulfite is the magnesium salt of sulfurous acid with the formula MgSO3. Its most common hydrated form has 6 water molecules making it a hexahydrate, MgSO3·6H2O. When heated above 40 °C (104 °F), it is dehydrated to magnesium sulfite trihydrate, or MgSO3·3H2O.[1] The anhydrous form is hygroscopic, meaning that it readily absorbs water from the air.
