How do chromate and dichromate ions interconvert in aqueous solution?

Options

  1. AThey don't interconvert in aqueous solution.
  2. BIt depends on the temperature.
  3. CIt depends on the presence of air.
  4. DIt depends on the pH of the solution.

Correct answer

D. It depends on the pH of the solution.

Step-by-step solution

The chromates and dichromates are interconvertible in aqueous solution depending upon pH of the solution. The oxidation state of chromium in chromate and dichromate is the same.
