Used as a strong oxidizing agent in analytical chemistry for titrations, especially in the determination of iron and other reducing agents. Commonly employed in redox reactions due to its stable and reversible Ce⁴⁺/Ce³⁺ couple. Also utilized in industrial processes for wastewater treatment, where it helps oxidize pollutants and organic contaminants. Plays a role in the synthesis of catalysts and in electrochemical applications, including fuel cells and sensors. Its hydrate form ensures better solubility and handling in aqueous systems.
