Write two oxidizing and two reducing properties of `H_(2)O_(2)`.

Explanation

1. `H_(2)O_(2)` decolourises acidified potassium permanganate.
`2 KMnO_(4) + 3H_(2)SO_(4) + 5H_(2)O_(2) rarr K_(2)SO_(4) + 2MnSO_(4) + 8H_(2)O + 5O_(2)`
2. Chlorine and bromine are reduced by `H_(2)O_(2)` to corresponding hydrogen chloride or hydrogen bromide.
`Cl_(2) + H_(2)O_(2) rarr 2HCl + O_(2)`
`Br_(2) + H_(2)O_(2) rarr 2HBr + O_(2)`
3. Moist silver oxide is reduced to silver by hydrogen peroxide.
`Ag_(2)O + H_(2)O_(2) rarr 2Ag + H_(2)O + O_(2)`
4. In alkaline solution ferric salts are reduced to ferrous salts.
`2Fe^(3+) + H_(2)O_(2) + OH^(-) rarr 2Fe^(2+) + 2H_(2)O + O_(2)`
5. Reduces `O_(3) "to" O_(2)`
`O_(3) + H_(2)O_(2) rarr 2O_(2) + H_(2)O`
