`0.108g` of finely divided copper was treated with an excess of ferric sulphate solution until copper was comnpletely dissolved. The solution after the addition of excess dilute sulphuric acid required `33.7mL` of `0.1N KMnO_(4)` for complete oxidation. Find the equaction which represents the reaction between metallic copper and ferric sulphate solution. At wt. of `Cu = 63.6` and `Fe = 56`.

Answer» Correct Answer - `Cu + Fe_(2)(SO_(4))_(3) rarr CuSO_(4) + 2FeSO_(4)`
