  • Sodium sulfite (sodium sulphite) is a soluble compound of sodium.
  •  Its chemical formula is Na2SO3.
  •  It has a molecular weight of 126.04.
  • It is a product of SO2 scrubbing, a part of the flue gas desulfurization process.
  • Sodium sulfite by reacting sodium carbonate solution with sulfur dioxide.
  • Production of sodium sulfite begins with the burning of sulfur to form sulfur dioxide, or SO2 gas.
  • Generated SO2 gas is introduced to sodium carbonate liquor in the absorber.
  • By controlling the pH and the operating mode of the crystallizer, sodium sulfite is produced.
  • Coal consumption for sodium sulfide production is reduced considerably when the optimized sodium sulfide production process replaces the conventional process and impacts on the environment from the sulfide would have been reduced by about 30% if sodium sulfide from an optimized process had been used in the process.
  • Dechlorination of chlorinated water discharges is accomplished by the addition of tablets comprised of 90% sodium sulfite to the discharge flow.
  • The alkaline sulfide system is one of these and is essentially a mixture of sodium sulfide and sodium hydroxide, This is a unique hydrometallurgical system as it is a very selective lixiviant for the distinct leaching technique of tin, gold, antimony, arsenic and mercury.
  • This method is used to determine sodium sulfite in a Process ECN-2, ECP-2D, or VNF/RVNP Color Developer sample.
  • The sulfite content is determined by reacting the sample with excess iodine (liberated from the reaction of potassium iodine under acidic conditions).
  • Sodium sulfite is primarily used in the pulp and paper industry.
  • It is used in water treatment as an oxygen scavenger agent, in the photographic industry to protect developer solutions from oxidation and (as hypo clear solution) to wash fixer (sodium thiosulfate) from film and photo-paper emulsions, in the textile industry as a bleaching, desulfurizing and dechlorinating agent and in the leather trade for the sulfitization of tanning extracts.
  • It is used in the purification of TNT for military use.
  • It is used in chemical manufacturing as a sulfonation and sulfomethylation agent.
  • It is used in the production of sodium thiosulfate.
  •  It forms a bisulfite adduct with aldehydes, and with ketones forms a sulfonic acid.
  • It is used to purify or isolate aldehydes and ketones.
