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 43.9 mL43.9 mL of 0.310 M Na2S2O3(aq)0.310 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.
