Suppose a student needs to standardize a sodium thiosulfate, Na, S,03, 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 concentration of Na, S,O,. The end point of the titration is reached after 0.85 mL of Na, S, 0, is dispensed from a microburet. What is the concentration of the standard sodium thiosulfate solution? concentration = M
