The iodine solution is usually made in the presence of iodide ion, forming the more stable triiodide ion, Is, giving the following overall reaction CeHsOc(aq) + Is (aq) + H₂O(1)→ CHO(aq) + 31-(aq) + 2H+(aq) The titration is carried out in the presence of starch, which forms a dark blue complex with the excess iodine when the endpoint is reached. Ascorbic acid can be used to standardize the iodine solution. A 0.315 g sample of ascorbic acid was titrated with iodine solution, requiring 30.2 mL to reach the endpoint. Calculate [ls], the molar concentration of Is ion in the solution. O L Tab En Esc 79°F Sunny ! 1 Q A N FI @ 2 W S F2 X # 3 E D…
