Potassium pyrosulfate

Description:
Potassium pyrosulfate, with the chemical formula K2S2O7 and CAS number 7790-62-7, is an inorganic salt characterized by its white crystalline appearance. It is a strong oxidizing agent and is soluble in water, forming a solution that can be acidic due to the release of sulfuric acid upon hydrolysis. This compound is often used in analytical chemistry and as a reagent in various chemical syntheses. Its properties include a high melting point and stability under normal conditions, although it can decompose when heated, releasing sulfur oxides. Potassium pyrosulfate is also utilized in the production of other potassium salts and in the preparation of certain catalysts. Due to its oxidizing nature, it must be handled with care, as it can react vigorously with reducing agents and organic materials. Proper safety measures, including the use of personal protective equipment, are essential when working with this compound in laboratory settings.
