Sodium bisulfite (NaHSO3) is a chemical compound widely used as a food additive. The bisulfite salt can be prepared by bubbling sulfur dioxide in a solution of sodium carbonate in water. Sodium bisulfite in contact with chlorine bleach will generate heat and form sodium bisulfate and sodium chloride. Synonyms: Disodium Disulfite, Sodium Bisulphite, Sodium Hydrogen Sulphite, Sodium Hydrogen Sulfite. CAS No: 7631-90-5. Molecular Formula: NaHSO3. Molar Mass: 104.06 g/mol.
