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)toK_(2)SO_(4)+2MnSO_(4)+3H_(2)O+5[O]),(H_(2)O_(2)+[O]toH_(2)P+O_(2)xx5):})/(2KMnO_(4)+3H_(2)SO_(4)+5H_(2)O_(2)toK_(2)SO_(4)+2KnSO_(4)+8H_(2)O+5O_(2)))/`
1 mole of `KMnO_(4)` requires 5/2 mol of `H_(2)O_(2)`.
