0.0026 M I_(2) solution having unknown volume is reacted with excess of ferrous thiocynate solution to form Fe_(2)O_(3),SO_(4)^(2-),CN^(-) along with I^(-) . If all the sulphate ions formed are precipitated using BaCl_(2) such that 16776 gm of BaSO_(4) is obtained, calculate volume of I_(2) consumed in litre. (At. mass : Ba=137)
