Hydrogen peroxide acts both as an oxidiz...

Hydrogen peroxide acts both as an oxidizing agent as a reducing agent in alkaline solution towards certain first row transition metal ions. Illustrate both these properties of `H_(2)O_(2)` using chemical equations.

Verified by Experts

Oxidising agent : `2Cr(OH)_(3)+4NaOH+3H_(2)O_(2)to2Na_(2)CrO_(4)+8H_(2)O`
Here, `Cr^(3+)"gets oxidized to"Cr^(6+)`
Reducing : `2K_(3)[Fe(CN)_(6)]+2KOH+H_(2)O_(2)to2K_(4)[Fe(CN)_(4)]+2H_(2)O+O_(2)`
Here , `Fe^(3+)` gets reduced to `Fe^(2+).`

How would you account for the following: (i) Cr^(2+) is reducing in nature while with the same d-orbital configuration (d^4) Mn^(3+) is an oxidising agent. (ii) In a transition series of metals, the metal which exhibits the greatest number of oxidation state occurs in the middle of the series.
