WebThe 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: (12.12.2) 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. Web2CrO 4 2– (aq) (yellow) + 2H + (aq) ⇌ Cr 2 O 7 2– (aq) (orange) + H 2 O(l) The addition of acid encourages the equilibrium towards the right, producing more orange-coloured dichromate(VI) ions. The addition of hydroxide ions causes the concentration of hydrogen ions to decrease, and this brings the equilibrium back to the left-hand side ...
