The amount of I-3 (aq) I3 - (aq) in a solution can be determined by titration with a solution containing a known concentration of S2O2-3 (aq) S2O32 - (aq) (thiosulfate ion). The determination is based on the net ionic equation 2S2O2-3 (aq) + I-3 (aq) ⟶S4O2-6 (aq) + 3I - (aq) 2S2O32 - (aq) + I3 - (aq) ⟶S4O62 - (aq) + 3I - (aq) Given that it requires 25.2 mL25.2 mL of 0.470 M Na2S2O3 (aq) 0.470 M Na2S2O3 (aq) to titrate a 10.0 mL10.0 mL sample of I-3 (aq), I3 - (aq), calculate the molarity of I-3 (aq) I3 - (aq) in the solution.
