Cerium (III) nitrate hexahydrate (Ce(NO3)3.6H3O) is an inorganic compound with cerium in the oxidation state +3. This crystalline solid is an important reagent in various scientific and industrial processes. It is a colorless to pale yellow crystal that is freely soluble in water, slightly soluble in alcohol, and hygroscopic, absorbing moisture from the air. In 1839, Swedish chemist Carl Gustaf Mosander isolated cerium from the mineral ceria. As the unique properties of cerium became known, especially in redox reactions, the compound cerium (III) nitrate hexahydrate began to be used. Cerium can exist in a variety of oxidation states and is valuable in a variety of applications.
Cerium (III) nitrate is widely used as a catalyst for redox reactions due to its ability to switch between Ce(III) and Ce(IV) states. This redox ability makes it essential in organic synthesis, promoting reactions such as oxidation, reduction, and coupling reactions.
