Product Description

Potassium Metabisulfite with CAS 16731-55-8

Potassium pyrosulfite is a chemical with the molecular formula K2S2O5. Potassium pyrosulfite is slowly oxidized into potassium sulfate in the air and is oxidized more quickly in the wet air. Exposure to acids releases highly irritating sulfur dioxide gases. It's strongly reductive. Decompose when heated to 190 ℃, ground into a powder heat burns. Potassium pyrosulfite is decomposed by acid to form sulfur dioxide. Easily soluble in water, slightly soluble in ethanol, insoluble in ether. Potassium pyrosulfite is stable in dry air and can release sulfur dioxide easily in humid air. Water solution can be oxidized by air to potassium sulfate.
