Question

Standardization of Sodium Thiosulfate In one trial of the standardization of a Na2S2O3 solution, a 10.00 mL volume of 5.00x10-3 M KIO3 is pipetted into a 250 mL Erlenmeyer flask. The solution is titrated to the endpoint with 15.87 mL of the Na2S2O3 solution. What is the molar concentration of this sodium thiosulfate solution?
