Suppose in an experiment to determine the amount of sodium hypochlorite in bleach, 0.0000552 mol KIO3 were titrated with an unknown solution of NazS2O, and the endpoint was reached after 17.80 mL. The reaction involved is IO3 (aq) + 6S203 (aq) + 6 H (aq) I (aq) + 3 S,O (aq) How many moles of Na S2O3 did this require? Type answer:
