CH3CHO + 2 Cu(OH)2 → CH3COOH + Cu2O + 2 H2O | Traloitructuyen.com kiến thức mới năm 2023

This is an oxidation-reduction (redox) reaction:

[external_link offset=1]

2 Cu^II + 2 e^– → 2 Cu^I (reduction)

C^I – 1 e^– → C^II (oxidation)

C^I + 3 e^– → C^-II (reduction)

C^-III – 5 e^– → C^II (oxidation)

C^-III – 1 e^– → C^-II (oxidation)
