Cerous oxalate, Ce2(C2O4)3.10H2O, may readily be obtained by double decomposition as a white, crystalline powder. The oxalate when air-dried has the above composition, but crystalline hydrates containing 3H2O,9H2O, and 11H2O have also been prepared.
Cerous oxalate is transformed into a crystalline oxalochloride when it is dissolved in hot, concentrated hydrochloric acid, and the solution allowed to cool. |
