Determination of Ethanol Concentration in Aqueous Solutions Introduction This method uses a redox titration to find the concentration of ethanol in an aqueous solution. The ethanol is oxidised to ethanoic acid by reacting it with an excess of potassium dichromate in acid. 2 Cr 2 O 7 2− + 16 H+ + 3 C 2 H 5 OH → 4 Cr3+ + 11 H 2 O + 3 CH 3 COOH
