a. Strong Reducing Agent: Rongalite possesses strong reducing properties and is often oxidized to sodium sulfite and sodium sulfate.
b. Instability and Decomposition: Rongalite is inherently unstable and decomposes under certain conditions:
Rapid oxidation in air: 2Na₂S₂O₄ + O₂ → 2Na₂SO₄ + 2SO₂↑
Sodium Hydrosulfite Reaction in aqueous solution: 2Na₂S₂O₄ + H₂O → Na₂S₂O₃ + 2NaHSO₃
Decomposition in moist air: 2Na₂S₂O₄ + O₂ + 2H₂O → 4NaHSO₄
Rapid decomposition at temperatures >90°C: 2Na₂S₂O₄ → Na₂SO₃ + Na₂S₂O₅
Ignition and spontaneous combustion at temperatures above 250°C.
c. Sodium Hydrosulfite Decomposition in Acidic/Basic Media:
Decomposes rapidly in acidic media: Na₂S₂O₄ + H₂SO₄ → Na₂SO₄ + SO₂↑ + S + H₂O
Relatively stable in alkaline media, but decomposes in strong alkali: 3Na₂S₂O₄ + 6NaOH → 5Na₂SO₃ + Na₂S + 3H₂O
