Ph of sodium sulfite solution
WebSodium sulfite is decomposed by even weak acids, giving up sulfur dioxide gas. Na 2 SO 3 + 2 H + → 2 Na + + H 2 O + SO 2. A saturated aqueous solution has pH of ~9. Solutions exposed to air are eventually oxidized to sodium sulfate. If sodium sulfite is allowed to crystallize from aqueous solution at room temperature or below, it does so as a ...
