Solution

Q.
(I) $H_{2} O_{2} + O_{3} ⟶ H_{2} O + 2 O_{2}$

(II) $H_{2} O_{2} + {Ag}_{2} O ⟶ 2 Ag + H_{2} O + O_{2}$

Role of hydrogen peroxide in the above reactions is respectively [2014]

Solution

Q.
(I) $H_{2} O_{2} + O_{3} ⟶ H_{2} O + 2 O_{2}$

(II) $H_{2} O_{2} + {Ag}_{2} O ⟶ 2 Ag + H_{2} O + O_{2}$

Role of hydrogen peroxide in the above reactions is respectively [2014]

1 oxidizing in (I) and reducing in (II)

2 reducing in (I) and oxidizing in (II)

3 reducing in (I) and (II)

4 oxidizing in (I) and (II)

Ans.
(3)

$H_{2} O_{2}$ acts as reducing agent in both the reactions in which $O_{2}$ is evolved.
