Answer»

Solution :`(a) (i)2KMnO_(4) + underset((Dil))(3H_(2)SO_(4)+10KI to K_(2)SO_(4)+2MnO_(4)+8H_(2)O+5I_(2)`
(ii) `2KMnO_(4)+underset((Dil))(3H_(2)SO_(4))+5H_(2)S to K_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5S`
`(iii) 2KMnO_(4)+underset((Dil))(8H_(2)SO_(4))+10FeSO_(4) to K_(2)SO_(4)+2MnSO_(4)+5Fe_(2)(SO_(4))_(3)+5H_(2)O`
(B) STRUCTRUE of `MnO_(4)^(-)`
