For decolourisation of `1 "mol of" KMnO_(4)`, the moles of `H_(2)O_(2)` required is

A

`1//2`

B

`3//2`

C

`5//2`

D

`7//2`

Text Solution

Verified by Experts

The correct Answer is:
C
`2KMnO_(4)+3H_(2)SO_(4)rarr K_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5[O]`
`[H_(2)O_(2)+O rarr H_(2)O + O_(2)]xx5`
Hence, 1 mole of `KMnO_(4)` requires 5/2 moles of `H_(2)O_(2)`
