Hydrogen peroxide is a powerful oxidising agent, both in the acidic and alkaline medium.
In acidic medium: `H_(2)O_(2)+2H^(o+)+2e^(ɵ)to2H_(2)O`
In alkaline medium: `H_(2)O_(2)+2e^(ɵ)to2overset(Theta)(O)H`
Hydrogen peroxide acts as a reducing agent towards powerful oxidising agents.
In acidic medium: `H_(2)O_(2)to2H^(o+)+O_(2)+2e^(ɵ)` In alkaline medium, however, its reducing nature is more effective.
`H_(2)O_(2)to2H^(o+)+O_(2)+2e^(ɵ)`
On addition of `H_2O_2` to accidified `KMnO_4, KMnO_4` gets decolourised due to

Options

A. oxidation of `KMnO_(4)`
B. reduction of `KMnO_(4)`
C. both oxidation and reduction
D. none of the above of `KMnO_(4)`

Answer

B

Explanation

`{:(2KMnO_(4)+3H_(2)SO_(4)toK_(2)SO_(4)+2MnSO_(4)+2MnSO_(4)+3H_(2)O+5[O]),(5H_(2)O_(2)+5[O]to5H_(2)O+5O_(2)),(ulbar(2KMnO_(4)^(ɵ)+3H_(2)SO_(4)+5H_(2)O_(2)toK_(2)SO_(4)+2MnSO_(4)+8H_(2)O+5O_(2))),(or 2MnO_(4)^(ɵ)+6H^(ɵ)+5H_(2)O_(2)to2Mn^(2+)+8H_(2)O+5O_(2)):}`
