Used as a strong oxidizing agent in analytical chemistry, particularly in redox titrations for the determination of iron and other reducing agents. It serves as a stable and reliable titrant in volumetric analysis due to its consistent oxidation potential and long shelf life in solution. Commonly employed in industrial processes for the oxidation of organic compounds, including the treatment of wastewater and removal of pollutants. Also utilized in electroplating and as a catalyst in certain chemical reactions where controlled oxidation is required. Its tetrahydrate form offers ease of handling and accurate weighing in laboratory settings.
