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

Explanation

`H_(2)O_(2)`-oxidising agent
`Fe^(2+) + H_(2)O_(2) to Fe^(3+) + H_(2)O`(Acidic medium)
Ferrous ion is oxidised by `H_(2)O_(2)` to Ferric ion
The balanced equation is `Fe^(3+) + e^(-)xx2`
`H_(2)O_(2) + 2H^(+) + cancel(2e^(-)) to 2H_(2)O`
`2 Fe^(2+) to 2 Fe^(3+) +cancel(2e^(-))`
`H_(2)O_(2) + 2H^(+) to 2H_(2)O`
`2Fe^(2+) + H_(2)O_(2) + 2H^(+) to 2Fe^(3+) + 2H_(2)O`
