CH3CHO + 2 CuO → CH3COOH + Cu2O - Balanced Equation

This is an oxidation-reduction (redox) reaction:

2CuII+2e-→2CuI(reduction)

CI-1e-→CII(oxidation)

CI+3e-→C-II(reduction)

C-III-5e-→CII(oxidation)

C-III-1e-→C-II(oxidation)

CuO is an oxidizing agent, CH3CHO is a reducing agent, CH3CHO is an oxidizing agent, CH3CHO is a reducing agent, CH3CHO is a reducing agent.
