Question 1

Based on the balanced chemical equation shown below, determine the mass percent of Fe3+ in a 0.6450 gram sample of iron ore, if 22.40 mL of a 0.1000 M stannous chloride, SnCl2(aq), solution is required to completely react with the Fe3+ present in the ore sample. The chemical equation for the reaction is:

2 Fe3+(aq) + Sn2+(aq) → 2 Fe2+(aq) + Sn4+(aq).
