The blood alcohol (C2H5OH) level can bedetermined by titrating a sample of blood plasma with an acidicpotassium dichromate solution, resulting in the production ofCr3+(aq) and carbon dioxide. The reaction canbe monitored because the dichromate ion(Cr2O72-) is orange in solution, and the Cr3+ ion is green. The unbalanced redox equationis shown below.
Cr2O72-(aq) +C2H5OH(aq) → Cr3+(aq) +CO2(g)
If 31.05 mL of 0.0600 M potassium dichromate solution isrequired to titrate 30.0 g of blood plasma, determine the masspercent of alcohol in the blood.
