(a) H 2 O 2+ O 3 arrow H 2 O +2 O 2 In this reaction, O 3 is reduced into O -2 ion. (b) H 2 O 2+ Ag 2 O arrow 2 Ag + H 2 O + O 2 In this reaction, Ag 2 O is reduced to Ag. Hence, H 2 O 2 acts as reducing agent in both the reactions.

Q. (a) $H_{2} O_{2} + O_{3} \to H_{2} O + 2 O_{2}$
(b) $H_{2} O_{2} + A g_{2} O \to 2 A g + H_{2} O + O_{2}$
Role of hydrogen peroxide in the above reactions is respectively -

Oxidizing in (a) and reducing in (b)

Reducing in (a) and oxidizing in (b)

Reducing in (a) and (b)

Oxidizing in (a) and (b)

(a) $H_{2} O_{2} + O_{3} \to H_{2} O + 2 O_{2}$
In this reaction, $O_{3}$ is reduced into $O^{- 2}$ ion.
(b) $H_{2} O_{2} + A g_{2} O \to 2 A g + H_{2} O + O_{2}$
In this reaction, $A g_{2} O$ is reduced to $A g$ .
Hence, $H_{2} O_{2}$ acts as reducing agent in both the reactions.
