An aqueous ethylene glycol (HOCH, CH, OH, FW = 62.07 g/mol) solution with a mass of 220.9 mg is titrated with 33.7 mL of 0.0839 M Ce+ in 4 M HCIO,. The solution is held at 60 °C for 15 min to oxidize the ethylene glycol to formic acid ( HCO,H) and carbon dioxide. The excess Ce+ is titrated with 11.03 mL of 0.0447 M Fe2+ to a ferroin end point. What is the mass percent of ethylene glycol in the unknown solution? 9.2 mass percent = |% Incorrect
