yellow or orange-yellow crystalline powder. Soluble in inorganic acid, slightly soluble in water, the solution is Brown yellow, insoluble in acetic acid.
Cerium hydroxide precipitates were first prepared using a mixture of rare earth cerium and fluoride. After dissolving with sulfuric acid, ammonium sulfate was added to prepare Ceric Ammonium sulfate.
The reagent was analyzed, and the trace silver ion was measured. Used as an oxidant in volumetric analysis.
