The amount of I3-(aq) in a solution can be determined by titration with a solution containing a concentration of S2O32-(aq). The determination is based on the net ionic equation.
Given that it requires 35.8 mL of 0.350 M Na2S2O3(aq) to titrate a 30.0 mL sample of I3-(aq), calculate the molarity of I3-(aq) in the solution.
