Question 30 Suppose you standardize a Na25203 solution by dissolving 25.0 mg of KIO3 in acid and allow it to react with excess KI. The triiodide produced is then titrated with NazS203 solution, requiring 30.00 mL to reach the starch/triiodide end point. Determine the molarity of the thiosulfate solution considering the following reaction: 103 + 81 + 6 H* - 3 13 + 3 H20 13 + 2 S2032- - 31 + S4062- O a. 0.0467 mol/L O b.0.02335 mol/L O c. 0.04675 mol/L O d. 0.0234 mol/L A Moving to another question will save this response. « < Question 30 of 40 EN 18°C Sunny ) 202 近
