WebSodium sulfite (CAS 7757-83-7) is an odorless, solid white powder with a salty sulfurous taste that is soluble in water. It is primarily used as a food preservative (e.g., to prevent dried fruit from discoloring) and as an antioxidant. In the past, sodium sulfite was used to make pulp in the paper industry, but its use now accounts for less ... 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 ...
