Cerium(IV) sulfate (Ce(SO4)2)-Powder

Characteristic

 

Cerium(IV) sulfate, also called ceric sulfate, is an inorganic compound. It exists as the anhydrous salt Ce(SO4)2 as well as a few hydrated forms: Ce(SO4)2(H2O)x, with x equal to 4, 8, or 12. These salts are yellow to yellow/orange solids that are moderately soluble in water and dilute acids. Its neutral solutions slowly decompose, depositing the light yellow oxide CeO2. Solutions of ceric sulfate have a strong yellow color. The tetrahydrate loses water when heated to 180-200 °C.

Application




Cerium(IV) sulfate is a redox indicator and is used in analytical chemistry for redox titrations. In ionized form, ceric ion acts as a strong oxidizer under acidic conditions. It is also used to prepare spherical-like nanoparticles CeO2, nanoparticles for NO reductions' reactions.
