oxidation state of i2 is 0 but after reaction changes to -1 therefore iodine is reduced by h2o2 and h2o2 acts as a reducing agent

Hey dear,
● Reducing character of H2O2 -
- H2O2 can act as reducing agent in any (acidic, alkaline or neutral) medium.
- In alkaline medium, hydrogen peroxide reduces halogens to halide ions.
- For example, hydrogen peroxide reduces iodine gas (OS => 0) to iodide ion (OS => -1).
I2 + H2O2 + 2NaOH --> 2NaI + 2H2O + O2
Hope this helped you.
Keep asking.
