When `KMnO_(4)` reacts with acidified `FeSO_(4)`A. Only `FeSO_(4)` is oxidisedB. Only `KMnO_(4)` is oxidisedC. `FeSO_(4)` is oxidised and `KMnO_(4)` is reducedD. none of these |
Answer» Correct Answer - C `FeSO_(4)` is oxidised and `KMnO_(4)` is reduced. `({:(2KMnO_(4) +3H_(2)SO_(4)toK_(2)SO_(4)+2MnSO_(4)),([2FeSO_(4)+ H_(2)SO_(4)toFe_(2)(SO_(4))_(3)+2H]xx5):})/(2KMnO_(4)+ 8H_(2)SO_(4)+10Fe SO_(4)to K_(2)SO_(4)+ 2MnSO_(4)+ 5Fe_(2) (SO_(4))_(3)+8H_(2)O)` In this reaction oxidation state of Mn is changing from +7 to +2 while oxidation state of Fe is changing from +2 to +3. |
