Titrimetric Determination of Hypo Index, Sulfite

sodium bisulfite is a mixture of sodium sulfite, sodium metabisulfite and water. Its purity, as determined by an iodine titration and expressed as sodium bisulfite, is approximately 107.5 percent with a minimum assay of 105 percent. If it were pure sodium metabisulfite, it would assay 110 percent (ANSI PH4.276-1987) as sodium bisulfite.
