Number of electrons transferred in each case when KMnO_(4) acts as an oxidising agent to give MnO_(2),Mn^(+2), Mn(OH)_(3) and MnO_(4)^(2-) are respectively:

Volumetric titrations involving KMnO_(4) , are carried out only in presence of dilute H_(2)SO_(4) but not in the presence of HCI or HNO_(3) This is because oxygen produced from KMnO_(4) + dil: H_(2)SO_(4) , is used only for oxidizing the reducing agent. Moreover, H2SO4 does not give any oxygen of its own to oxidize the reducing agent. In case HCI is used, the oxygen produced from KMnO_(4) + HCI is partly used up to oxidize HCI and in case HNO_(3) is used, it itself acts as oxidizing agent and partly oxidizes the reducing agent. KMnO_(4) , in various mediums gives following products Mn^(7+)overset(H^(+))toMn^(2+) Mn^(7+)overset(H_(2)O)toMn^(4+) Mn^(7+)underset(OH^(-))toMn^(6+) QNumber of electrons transferred in each case when KMnO_(4) acts as an oxidizing agent to give MnO_(2) , Mn^(++) Mn(OH)_(3) , and MnO_(4)^(2-) are respectively
