Question

Write chemical reactions to justify that hydrogen peroxide can function as an oxidising as well as reducing agent.

Answer 1

(A) Chemical reactions justifying oxidizing nature of $H_2{O}_2$ are as follws:
$H_2{O}_2+2KI\to 2KOH+I_2$
$Hg+H_2{O}_2\to HgO+H_{2}O$
(B) Chemical reactions that justify the reducing nature of $H_2{O}_2$ are as follows:
$H_2{O}_2+C{l}_2\to 2HCl+O_2$
$Pb{O}_2+H_2{O}_2\to PbO+H-2O+O_2$
