Potassium Metabisulfite
CAS Number: 16731-55-8
Molecular Formula: K2S2O5
Molecular Weight: 222.3
Potassium Metabisulfite
Potassium Metabisulfite USP Grade Specifications
K2S2O5 222.33
Disulfurous acid, dipotassium salt.
Dipotassium pyrosulfite CAS 16731-55-8
Potassium Metabisulfite contains an amount of K2S2O5 equivalent to not less than 51.8 percent and not more than 57.6 percent of SO2.
Identification: A solution (1 in 20) responds to the tests for Potassium and for Sulfite.
Iron: Dissolve 1.00 g in 14 mL of dilute hydrochloric acid (2 in 7), and evaporate on a steam bath to dryness. Dissolve the residue in 7 mL of dilute hydrochloric acid (2 in 7), and again evaporate to dryness. Dissolve the resulting residue in a mixture of 2 mL of hydrochloric acid and 20 mL of water, add 3 drops of bromine TS, and boil to expel the bromine. Cool, and dilute with water to 47 mL: the limit is 0.001%.
Heavy metals: Dissolve 2 g in 20 mL of water, add 5 mL of hydrochloric acid, evaporate on a steam bath to about 1 mL, and dissolve the residue in 25 mL of water: the limit is 0.001%.

DESCRIPTION
Potassium Metabisulfite occurs as white or colorless, free flowing crystals, crystalline powder, or granules. It gradually oxidizes in air to the sulfate. It is soluble in water, but it is insoluble in alcohol. Its solutions are acid to litmus.
REQUIREMENTS
Identification: A 1:10 aqueous solution gives positive tests for Potassium and for Sulfite.
Assay: Not less than 90.0% of K2S2O5.
Lead: Not more than 2 mg/kg.
Iron: Not more than 10 mg/kg.
Selenium: Not more than 5 mg/kg.
