Hydrogen peroxide is an oxidising agent. It oxidises ferrous ion to ferric ion and reduced itself to water. Write a balanced equation.

Explanation

`H_2O_2 ` - Oxidising agent
`Fe^(2+)+H_(2)O_(2) to Fe^(3+)+H_(2)O` (Acetic Medium)
Ferrous ion is oxidized by `H_2O_2` to Ferric ion
The balanced equation is `Fe^(2+)to Fe^(3+)+e^(-)xx2`
`H_2O_(2)+2H^(+)+2cancel(e^(-)) to 2H_(2)O`
`2Fe^(2+)to 2Fe^(3+)+cancel(2e^(-))`.
`(H_(2)O_(2)+2H^(+)to2H_(2)O)/(2Fe^(2+)+H_(2)O_(2)+2H^(+)to2Fe^(3+)+2H_(2)O)`
