WebJan 23, 2024 · The alcohol is heated under reflux with an excess of the oxidizing agent. When the reaction is complete, the carboxylic acid is distilled off. The full equation for the oxidation of ethanol to ethanoic acid is as follows: (3) 3 C H 3 C H 2 O H + 2 C r 2 O 7 2 − + 16 H + → 3 C H 3 C O O H + 4 C r 3 + + 11 H 2 O. The mechanism of chromyl chloride test is simple. On reacting potassium dichromate with sulphuric acid, chromate trioxide (oxidation state = +6) is formed. The colour of chromate trioxide (CrO3) varies from dark red to brown colour.
