2. Properties: Na₂SO₅

   • Physical properties: Sodium sulfite is a solid, white, odorless substance with a neutral PH.
   • Chemical properties: Sodium sulfite can react with acids to produce SO₂ gas, and can also be oxidized to Sodium sulfate. This substance is also easily decomposed by sunlight.

3. Common chemical reactions

   • Reaction with acid: Na₂SO₃ + H₂SO₄ -> Na₂SO₄ + H₂O + SO₂.
   • Oxidation reaction: 2Na₂SO₃ + O₂ -> 2Na₂SO₄.
   • Reaction with salt: Na₂SO₃ + 2NaCl + 2NaCl -> Na₂SO₄.

4. Synthesis of Na₂SO₅

   • Laboratory synthesis: Sodium sulfite can be synthesized by reacting Sodium hydroxide with SO₂.
   • Industrial synthesis: In industry, Sodium sulfite is usually produced by reacting Sodium hydroxide with sulfur dioxide under high temperature and pressure conditions.
