Balance the following equation by oxidation number method.KMnO_(4)+FeSO_(4)+H_(2)SO_(4)rarrK_(2)SO_(4)+MnSO_(4)+Fe_2(SO_(4))_(3)+H_(2)O |
Answer» Solution : (ii) `2KMnO_(4) + 10FeSO_(4) + H_(2)SO_(4) rarr K_(2)SO_(4) + MnSO_(4) + Fe_(2)(SO_(4))_(3) + H_(2)O`. (III) Balance the equation atomically (except O and H) and sulphate IONS. `2KMnO_(4) + 10FeSO_(4) + 8H_(2)SO_(4) rarr K_(2)SO_(4) + 2MnSO_(4) + 5Fe_(2)(SO_(4))_(3) + H_(2)O` (iv) Balance O atoms by multiplying `H_(2)O` by 8. `2KMnO_(4) + 10FeSO_(4) + 8H_(2)SO_(4) rarr K_(2)SO_(4) + 2MnSO_(4) + 5Fe_(2)(SO_(4))_(3) + 8H_(2)O` |
