1.	25mL of a solutioncontainingFe^(2+) and Fe^(3+) sulphate acidifed with H_(2)SO_(4) is reducedby 3g of metallliczinc. The dsolution required 34.25mL of N//10 solution of K_(2)Cr_(2)O_(7) for oxidation. Beforereduction with zinc, 25mL of the same solution. Calculate the strengthof FeSO_(4) and Fe_(2) (SO_(4))_(3) in solution.
Answer» ANSWER :`FeSO_(4) = 13.64g//"LITRE'`, `Fe_(2)(SO_(4))_(3) = 9.45g//"litre"`
