Given reasons in two or there sentences only for the following Hydrogen peroxide acts as an a reducing agent .

Explanation

In `H_(2)O_(2)` the oxidation number of oxygen is-1 so it can be increased up to 0 and decreased up `to-2` Hence it acts as a reducing as well as an oxidising agent As oxidising agent
`H_(2)O_(2)+2e^(-) rarr2OH^(Theta)`
`2Cr(OH)_(3) +4NaOH+3H_(2)O_(2) rarr2Na_(2)CrO_(4)+8H_(2)O`
The oxidation number of chromium increases from `+3` to `+6` As reducing agent
`H_(2)O_(2)+2OH^(Theta)rarrO_(2)+2H_(2)O+2e^(-)`
`2K_(3)[Fe(CN)_(6)]+2KOH+H_(2)O_(2) rarr2K_(4)[Fe(CN)_(6)]+2H_(2)O+O_(2)`
The oxidation number of iron decreases from `+3 to +2` .
