In acid medium, both `KMnO_(4) " and " K_(2)Cr_(2)O_(7)` act as oxidising agents. Which among the following is correct about the oxidising behaviou ?

A

`KMnO_(4) gt K_(2)Cr_(2)O_(7)`

B

`KMnO_(4) lt K_(2)Cr_(2)O_(7)`

C

`KMnO_(4) = K_(2)Cr_(2)O_(7)`

D

Cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
A
`2Koverset(+7)(MnO_(4))+3H_(2)SO_(4)to K_(2)SO_(4)+2overset(+2)(MnSO_(4))+3H_(2)O+5[O]`
Change in oxidation number=10
`K_(2)overset(+12)(Cr_(2)O_(7))+4H_(2)SO_(4)to K_(2)SO_(4)+overset(+6)(Cr_(2))(SO_(4))_(3)+4H_(2)O+3[O]`
Change in oxidation number = 6
