A mixture containing iodide is analyzed by the Volhard method. 0.6712 g of the sample is reacted with 50.00 mL of 0.05619 M AGNO3. The precipitate formed is removed by filtration and the excess Ag+ is back titrated with KSCN 0.05322 M, requiring 35.15 mL to reach the end point. Calculate the concentration of iodide in the sample in parts per million (mg/kg).
