  1. Properties: MgSO3

2.1 Physical properties of MgSO3
State: Solid
Color: White
Odor: Odorless
pH level: Neutral
2.2 Chemical properties of MgSO3: MgSO3 in anhydrous form has antioxidant and antibacterial properties. It can decompose under high temperature, producing magnesium oxide (MgO) and sulfur dioxide (SO2).

  1. Common chemical equations involving MgSO3:
    MgSO3 does not participate in many chemical reactions. However, it can react with strong acids like sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4) and water.

  2. Synthesis of MgSO3:

4.1 Laboratory preparation of MgSO3: Heat magnesium oxide (MgO) with sulfur dioxide (SO2) in an air environment.
4.2 Industrial preparation of MgSO3: MgSO3 is commonly produced by reacting magnesium oxide (MgO) or magnesium hydroxide (Mg(OH)2) with sulfur dioxide (SO2) in water.
