Solution

The correct option is C $A g_{2} O (moist) + H_{2} O_{2} \to 2 A g + H_{2} O + O_{2}$
In (C) option, it reduces $A g$ from $+ 2$ to $0$ .
While in rest all it is acting as oxidising agent.
(A) oxidises $S$ from $- 2$ to $+ 6$
(B) oxidises $S$ from $+ 4$ to $+ 6$
(D) oxidises $I$ from $- 1$ to $0$ .

Which of the following reaction shows the reduction reaction of $H_{2}$ $O_{2}$ ?

In the reaction $A g_{2} O + H_{2} O_{2} \to 2 A g + H_{2} O + O_{2} . H_{2} O_{2}$ acts as :

H_{2} O_{2}

A g_{2} O + H_{2} O_{2} \to 2 A g + H_{2} O + O_{2}

H_{2} O_{2} + O_{3} \to H_{2} O + 2 O_{2}

H_{2} O_{2} + A g_{2} O \to 2 A g + H_{2} O + O_{2}

(I) H_{2} O_{2} + O_{3} \to H_{2} O + 2 O_{2}

(I I) H_{2} O_{2} + A g_{2} O \to 2 A g + H_{2} O + O_{2}
