Chemical Properties
yellow odourless solid
Physical properties
White crystalline powder; orthogonal crystal system; the tetrahydrate is a yellow-to-orange powder which, on heating at 180°C, loses all molecules of water; density of tetrahydrate 3.91 g/cm3; anhydrous salt decomposes at 350°C forming CeOSO
4; soluble in water (decomposes); soluble in dilute H
2SO
4 and other concentrated mineral acids.
Uses
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.
Uses
calibrated against sodium oxalate, traceable to NIST SRM
Preparation
Cerium(IV) sulfate is prepared by heating cerium(IV) oxide, CeO
2 with concentrated H
2SO
4. Also it may be obtained by the reaction of H
2SO
4 with cerium carbonate:
Ce(CO
3)
2 + 2H
2SO
4 + H
2O → Ce(SO

2?4H
2O + 2CO
