The blood alcohol level can be determined by titrating a sample of blood plasma with an acidic potassium dichromate solution, resulting in the production of and carbon dioxide. The reaction can be monitored because the dichromate ion () is orange in solution, and the ion is green. The unbalanced redox equation is Cr2O72-(aq)+ C2H2OH(aq)= Cr3+(aq)+CO2(g) If 28.03 mL of 0.0379 M potassium dichromate solution is required to titrate 14.4 g of blood plasma, determine the mass percent of alcohol in the blood.
