Suppose a student needs to standardize a sodium thiosulfate, Na, S, O3, solution for a titration experiment. To do so, he or she will react it with a solution of iodine. The student adds a 1.00 mL aliquot of 0.0200 M KIO, solution to a flask, followed by 3 mL of distilled water, 0.2 g of solid KI, and 1 mL H, SO . The student then titrates the solution with sodium thiosulfate solution in order to determine the exact...
