Sodium Metabisulfite, 98% (SMBS1)

Sodium Metabisulfite, 98%

Sodium metabisulfite (SMBS) is commonly used for removal of free chlorine and as a biostatic. Other chemical reducing agents exist (e.g., sulfur dioxide), but they are not as cost-effective as SMBS. When dissolved in water, sodium bisulfite (SBS) is formed from SMBS: Na2S2O5 + H2O → 2 NaHSO3, then reduces hypochlorous acid according to: 2NaHSO3 + 2HOCl → H2SO4 + 2HCl + Na2SO4. In theory, 1.34 mg of sodium metabisulfite will remove 1.0 mg of free chlorine. In practice, however, 3.0 mg of sodium metabisulfite is normally used to remove 1.0 mg of chlorine.
