Toxic cyanide ions can be removed from wastewater by adding hypochlorite. 2 CN−(aq) + 5 OCl−(aq) + H2O(?) → N2(g) + 2 HCO3−(aq) + 5 Cl−(aq) If 1.50 ✕ 103 L of 0.125 M OCl− is required to remove the CN− in 3.4 ✕ 106 L of wastewater, what is the CN− concentration in the water in mg/L? How many milliliters of 0.575 M AgNO3 would you need to add to a 50.00 mL aliquot of the final solution (consider the volumes simply additive) to precipitate the chloride ions formed in the reaction?
