Question

H2O2 is an oxidising as well as reducing agent

Answer 1

Dear student!

Hydrogen peroxide has the ability to gain or lose electrons, as its oxygen atoms are in the -1 oxidation state. By gaining electrons it undergoes to the -2 oxidation state, and by losing electrons it undergoes to the zero oxidation state (i,e, as the element).

As an oxidising agent as:

H₂O₂ + H₂S ----> 2H₂O + S

As a reducing agent:

H₂O₂ + Cl₂-------> 2HCl + O₂
