Question

Write chemical reactions to justify h2o2 can function as an oxidising as well as reducing agent

Answer 1

Hey mate‼‼

Ur answer is here...

Hydrogen Peroxide as an Oxidizing and a Reducing Agent. Hydrogen peroxide in acid solution is oxidized with KMnO4 and reduced with KI. When H2O2 serves as an oxidizing agent, the oxygen is reduced to H2O. When H2O2 serves as a reducing agent, the oxygen is oxidized to O2 and bubbles are noticed.

Answer 2

Answer:

Chemical reactions justifying oxidizing nature of

H 2O 2are as follws:

H 2 O 2+2KI→2KOH+I 2

Hg+H 2O 2→HgO+H 2O

Chemical reactions that justify the reducing nature of H 2O 2are as follows:

H 2O 2+Cl 2→2HCl+O 2

PbO 2+H 2O 2→PbO+H−2O+O
