Description

General description

Cerium(IV) sulfate tetrahydrate is a hydrated salt of cerium sulfate. Its molecule contains cerium ions coordinated with eight oxygen atoms. Its crystals have been reported to be orthorhombic.

Application

Cerium(IV) sulfate tetrahydrate may be employed in the synthesis of alkyl esters of oxo acids and oxo acids, via reaction with 2-substituted cycloalkanone. It may be used in the preparation of 0.01M cerium(IV) sulfate in 2M sulfuric acid solution.
