The concentration of an aqueous solution of Fe2+ can be determined by a redox titration with aqueous bromate ion, BrO3⁻:

6 Fe2+ (aq) + BrO3⁻ (aq) + 6 H⁺ (aq) → 6 Fe3+ (aq) + Br⁻ (aq) + 3 H2O (l)


Assume that the black spheres in the buret represent BrO3⁻ ions, the gray spheres in the flask represent Fe2+ ions, the concentration of the BrO3⁻ ions in the buret is 0.120 M, and the volumes in the buret and the flask are identical. What is the concentration of the Fe2+ in the flask, and what fraction of the BrO3⁻ solution in the buret must be added to the flask to react with all the Fe2+ ions?
◦ 0.0400 M Fe2+; 1/18 of the BrO3⁻ must be added.
◦ 0.0200 M Fe2+; 1/3 of the BrO3⁻ must be added.
◦ 0.0200 M Fe2+; 1/18 of the BrO3⁻ must be added.
◦ 0.0400 M Fe2+; 1/3 of the BrO3⁻ must be added.
