Question:

An aqueous glycerol solution weighing 100.0 mg was treated with 50.0 mL of 0.083 7 M Ce⁴⁺ in 4 M HClO₄ at 60°C for 15 min to oxidize the glycerol to formic acid:

CH, — CH— СH, | HCO,H OH ОН ОН Formic acid Glycerol FM 92.095

The excess Ce⁴⁺ required 12.11 mL of 0.044 8 M Fe²⁺ to reach a ferroin end point. What is the weight percent of glycerol in the unknown?
