Sodium Bisulfite (NaHSO3, CAS 7631-90-5) is usually supplied as a 38% to 40% yellowish solution with a sulfur dioxide odor and a specific gravity of about 1.33 to 1.48. It is used for dechlorination of water and wastewater, as an oxygen scavenger, to reduce hexavalent chromium, as a food preservative, and in pulp, textile and photographic processing. Tanks should be closed and vented, since SO2 off-gasses. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
