The blood alcohol C2 H; OH level can be determined by titrating a sample of blood plasma with an acidic potassium dichromate solution, resulting in the production of Cr*+ (aq) and carbon dioxide. The reaction can be monitored because the dichromate ion (Cr2 O,²) is orange in solution, and the Cr³* ion is green. The unbalanced redox equation is Cr2 O,2 (aq) + C2H; OH(ag) → Cr³* (ag) + CO2 (g) If 40.35 mL of 0.0711 M potassium dichromate solution is required to titrate 27.5 g of blood plasma, determine the mass percent of alcohol in the blood.
