Explain, in terms of ions, why an aqueous solution of potassium chromate conducts an
electric current

Explanation:
Aqueous solution of potassium chromate contains mobile ions that freely move from one place to another.
Potassium chromate solution contains charged particles. These charged particles are [tex]K^{+}[/tex] ions and [tex]CrO^{2-}_{4}[/tex] ions.
Therefore, due to the presence of these charged particles or ions a solution of potassium chromate is able to conduct electricity.
