Potassium Metabisulfite, also known as Pyrosulfurous Acid, Dipotassium Salt, Dipotassium Disulfate, and Potassium Pyrosulfate, has the chemical formula K2S2O5 or K2O5S2. It appears as a white granular or powdery solid with a sharp rotten-egg-like (Sulfur Dioxide) odor. It is soluble in Water and insoluble in Ethanol at ambient conditions. Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity. Due to its high purity, Potassium Metabisulfite, Lab Grade is highly recommended for labs and commercial applications.
