The strongest oxidizing agent among the ...

The strongest oxidizing agent among the following is : [HINT : Refer to Electrochemical series]

A

`K_(2)Cr_(2)O_(7)`

B

`MnO_(2)`

C

`KMnO_(4)`

D

`C1_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(Cr_(2) O_(7)^(2-)//Cr^(3+))^(@) = 1.33 V `, `E_(MnO_(2)//Mn^(2+))^(@) = 1.23V`, `E_(MnO_(4)^(-)//Mn^(2+)) = 1.51V`, `E_(Cl_(2)//(Cl^(-))) =1.36V`
`therefore E_(MnO_(4)^(-)//MN^(2+))^(@)` is highest , `KMnO_(4)` is the strongest oxidising agent.
