A person's blood alcohol (C2H5OH) level can be determined by titrating a sample of blood plasma with potassium dichromate solution. The balanced equation is:

16 H^+(aq) + 2 Cr2O7^2-(aq) + C2H5OH(aq) → 4 Cr^3+(aq) + 2 CO2(g) + 11 H2O(l)

a) If 35.46 mL of 0.05961 M Cr2O72- is required to titrate 28.00 g of plasma, what is the mass percent of alcohol in the blood?

Describe how 100 mL of 0.01 M KIO3 primary standard can be prepared from solid potassium iodate. Write a step-by-step procedure that includes supporting calculations and any equipment/glassware that is required.
