2 results about "Magnesium sulfite" patented technology

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. The anhydrous form is hygroscopic, meaning that it readily absorbs water from the air.
