The number of moles of `KMnO_(4)` that will be needed to react with one mole of sulphite ion in acidic solution is:

A

`2//5`

B

`3//5`

C

`4//5`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
A
`2MnO_(4)^(-)+5SO_(3)^(2-)+6H^(+) to2Mn^(2+)+5SO_(4)^(2-)+3H_(2)O`.
therefore2/5mole of `MnO_(4)^(-)` for one mole` SO_(3)^(2-)`.

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+) QThe number of moles of KMnO_(4) that will be needed to react with one mole of sulphite in an acidic solution is
