Everybody knows that Sodium Sulfite can be widely applied many ways. For example, it is used in the production of sodium thiosulfate. sodium sulfite is also applied in froth flotation of ores, oil recovery, food preservatives, making dyes.
Sodium sulfite(Na2SO3) is decomposed by even weak acids, giving up sulfur dioxide gas. 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 heptahydrate.
The heptahydrate crystals effloresce in warm dry air. Heptahydrate crystals also oxidize in air to form the sulfate. The anhydrous form is much more stable against oxidation by air.
