Description

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.

Chemical formula: Ce(SO4)2•xH2O

Molar mass: 404.304 (tetrahydrate)

Appearance: yellow-orange crystals (tetrahydrate)

Density:3.91 g/cm3 (tetrahydrate)

Melting point:350 °C (662 °F; 623 K) (decomposes)

Solubility in water:Soluble in small amounts, hydrolyzes in large amounts of water;21.4 g/100 mL (0 °C); 9.84 g/100 mL (20 °C); 3.87 g/100 mL (60 °C)

Solubility:soluble in dilute sulfuric acid

Magnetic susceptibility (χ):+37.0•10−6 cm3/mol

Cerium(IV) sulfate hydrate acts as oxidizing agent which is used for the generation of o-benzoquinone from catechol. It promotes the formation of radicals from dialkyl malonates, which undergo substitution reactions with furans and thiophenes.
