Sodium Sulfite, Sodium Metabisulfite and Sodium Bisulfite Solution
Sodium sulfite is primarily used as a pulping agent and de-chlorination agent by the paper industry. Other applications include its use to remove oxygen in boiler water and as an antioxidant in film processing. Sodium sulfite also serves to remove chlorine after bleaching of wood pulp.
Solvay Chemicals produces three grades of sodium metabisulfite; Technical, Food and Photographic. Its product is certified kosher.
Sodium bisulfite solution is very closely related to sodium metabisulfite, and as such it is used in similar applications.
