The amount of I3- (aq) in a solution can be determined by titration with a solution containing a known concentration of S2O32- (aq) (thiosulfate ion). The determination is based on the net ionic equation 2S2O32- (aq) + I3- (aq) yields to S4O62- (aq) + 3I- (aq) Given that it requires 34.2 mL of 0.500 M Na2S2O3 (aq) to titrate a 20.0 mL sample of I3- (aq), calculate the molarity of I3- (aq) in the solution.
