Q. In which of the following transformation, oxygen is not the reducing agent?
General Principles and Processes of Isolation of Elements
A
$Ag _2 O \rightarrow 2 Ag +\frac{1}{2} O _2$
B
$4 NH _3+3 O _2 \rightarrow 2 N _2+6 H _2 O$
C
$2 F _2+2 H _2 O \rightarrow 4 HF + O _2$
D
$2 AgNO _3+ H _2 O _2 \rightarrow 2 Ag +2 HNO _3+ O _2$
Solution:
$NH _3$ is oxidized to $N _2$ by $O _2$. Thus, $O _2$ is the oxidizing agent
In (a), (c) and (d), oxygen is a reducing agent
