Sodium sulphite forms a bisulfite adduct with aldehydes, and with ketones forms a sulfonic acid. It is used to purify or isolate aldehydes and ketones. Sulfite oxidation of sulfur in +4, which could rise or lower, so the sulfurous acid root there are both oxidizing and reducing
Sodium sulfite is easily weathered and oxidized to sulfate in air.And it will lose crystal water at 150 degrees. Reheat melting as a mixture of sodium sulfide and sodium sulfate.
Sodium Sulphite is also used as a preservative to prevent dried fruit from discoloring, and for preserving meats, and is used in the same way as sodium thiosulfate to convert elemental halogens to their respective hydrohalic acids.
