When metal A is placed in a solution containing ions of metal B, metal B plates out on the piece of A. If bubbles of H2 form when B is placed in acid, will they form if A is placed in acid?

  • Answer: Acid oxidizes metal B and metal B oxidizes metal A, so acid will oxidize metal A and bubbles will form when metal A is placed in acid. The same answer results if strength of reducing agents is considered. The fact that metal A is a better reducing agent than metal B indicates that if metal B reduces acid, then metal A will also reduce acid. Beatrice commented over 1 year ago
