What would be the product of electrolysis of a chromium cathode?

Question

Hello. I need to know the reaction product of the electrolysis of metallic chromium. Would it be enough to oxidize it to a +6 oxidation state and become chromic acid, or just chromic oxide or perhaps chromium hydroxide? Thank you.

Answer 1

There is one sovereign rule to remember: Oxidation occurs at the anode. Therefore, reduction occurs at the cathode. If chromium metal is the cathode, then the result is the production and buildup of more chromium at the cathode.

Do not be distracted by anything else. Once you memorize that oxidation occurs at the anode, you will know what pole is (+) and which is (-). You will know in which direction electrons flow over the external circuit, and which direction ions flow in the solution.
