A. To standardize a thiosulfate (S2O32-) solution, 10.00 mL of a 1.25Ã10â2 M IO3- solutionare treated with excess I- to generate I3- according to Equation 3 on page 162 in the lab manual. If 5.69 mL of the thiosulfate solution are required to reach the endpoint of the titration, what is the molarity of thiosulfate in the solution?
Using this equation: I3(aq)+2S2O32-(aq)->3I(aq) + S4O62-(aq)
