The amount of 1, (ag) in a solution can be determined by titration with a solution containing a known concentration of s,o (aq) (thiosulfate ion). The determination is based on the net ionic equation 25,0? (aq) + 13(aq) 5,0 (aq) + 31 (aq) Given that it requires 35.1 ml of 0.290 M Na S, 0, (aq) to titrate a 25.0 mL sample of T; (aq), calculate the molarity of 1; (aq) in the solution M
