Question 1

A disproportionation reaction is one in which:
◦ the equation is not balanced
◦ the same substance is oxidized and reduced
◦ more of one substance reacts than another
◦ water must be added
◦ both reactants are reduced

Question 2

A piece of iron wire weighing 1.63 g is converted to Fe2+(aq) and requires 21.9 mL of KMnO4 solution for its titration. What is the molarity of the KMnO4 solution? The reaction occurring during the titration is:

5 Fe2+ (aq) + MnO4- (aq) + 8 H+ (aq) → 5 Fe3+ (aq) + Mn2+ (aq) + 4 H2O

◦ 1.33 M
◦ 0.267 M
◦ 2.67 × 10-4 M
◦ 14.9 M
◦ 1.33 × 10-3 M
