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 primary standard in volumetric analysis due to its high stability and well-defined reactivity. Commonly employed in place of potassium permanganate when a more controlled oxidation is required, especially in acidic solutions. Also utilized in industrial processes for the treatment of wastewater and removal of pollutants through oxidation. Finds application in the synthesis of catalysts and in electrochemical studies as a mediator in oxidation reactions.
