Question

Which Oxoanion of chromium which is stable in acidic medium.

Answer 1

The answer is dichromate.

The oxoanion of chromium that is stable in acidic medium is dichromate. This is a relatively strong oxidizing agent and is soluble in water. The ionic properties result in the formation of various salts that make them suitable for oxidation-reduction reactions. Because of the solubility in water, it forms a precipitate that makes it easily identifiable in solutions and mixtures.
