Bromine water is a convenient agent for oxidizing cobaltous to cobaltic ions (see Chapter XV).
This hydroxide is soluble in well cooled acids, forming solutions which contain cobaltic salts, one of the most stable of which is the acetate.
The cobaltic salts corresponding to the oxide Co2O3 are generally unstable compounds which exist only in solution.
The double salts containing the metal in the cobaltic form are more stable than the corresponding single salts, and of these potassium cobaltinitrite, Co2(NO2)6.
Cobaltic hydroxide, Co(OH)3, is formed when a cobalt salt is precipitated by an alkaline hypochlorite, or on passing chlorine through water containing suspended cobaltous hydroxide or carbonate.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "cobaltic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
