The concentration of an aqueous solution of I3⁻ can be determined by a redox titration with aqueous sodium thiosulfate, Na2S2O3:

2 S2O32- (aq) + I3⁻ (aq) + → S4O62- (aq) + 3 I⁻ (aq)


Assume that the black spheres in the buret represent S2O32- ions, the gray spheres in the flask represent I3- ions, the concentration of the S2O32- 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 I3- in the flask, and what fraction of the S2O32- solution in the buret must be added to the flask to react with all the I3- ions?
◦ 0.0400 M I3-; 1/3 of the S2O32- must be added.
◦ 0.0600 M I3-; 2/3 of the S2O32- must be added.
◦ 0.0400 M I3-; 2/3 of the S2O32- must be added.
◦ 0.0600 M I3-; 1/3 of the S2O32- must be added.
