Examples
While chromium forms two series of salts, chromous salts are difficult to prepare and are of little importance.
The solution of chromous chloride must therefore be freed from the zinc by filtration in the absence of air.
In this manner a chromous acetate is obtained perfectly free from zinc.
A red precipitate of chromous acetate is formed, which is washed by decantation in water containing carbonic acid.
As but little chromous salt is decomposed by the oxygen such a washing apparatus may serve for many experiments.
