H_(2)O_(2) is a powerful oxidisingagent. It is an electron acceptor in acidic as well as in alkaline medium. It can also act as reducing agent towards oxidising agents. In alkaline medium, the reducing nature of H_(2)O_(2) is even more effective Decolourisation of acidified KMnO_(4) occurs when H_(2)O_(2) is added to it. This is due to

1.	H_(2)O_(2) is a powerful oxidisingagent. It is an electron acceptor in acidic as well as in alkaline medium. It can also act as reducing agent towards oxidising agents. In alkaline medium, the reducing nature of H_(2)O_(2) is even more effective Decolourisation of acidified KMnO_(4) occurs when H_(2)O_(2) is added to it. This is due to
Answer» Oxisation of `KMnO_(4)` REDUCING of `KMnO_(4)` Both oxidation and reduction of `KMnO_(4)`0 none of these Solution :(b) In the ACIDIC medium `KMnO_(4)` (violet ) is REDUCED to `K_(2)SO_(4) and MnSO_(4)` which are both colourless.
