The amount of I−3(aq) in a solution can be determined by titration with a solution containing a known concentration of S2O2−3(aq) (thiosulfate ion). The determination is based on the net ionic equation
2S2O2−3(aq)+I−3(aq)⟶S4O2−6(aq)+3I−( aq)
Given that it requires 25.1 mL of 0.250 M Na2S2O3(aq) to titrate a 20.0 mL sample of I−3(aq), calculate the molarity of I−3(aq) in the solution.

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
