What is the change in oxidation number of nitrogen in following conversion?
$\mathrm{NO}_3^{-} \longrightarrow \mathrm{NO}_2$
- +4 to +5
- +3 to +5
- +5 to +4
- -3 to +5
Solution
Oxidation number of Nitrogen in
$\underset{\mathrm{x}}{\mathrm{NO}_3^{-}} \Rightarrow \mathrm{x}-2 \times 3=-1$
$\begin{aligned} & x=+5 \\ & \mathrm{NO}_2 \Rightarrow \mathrm{y}-2 \times 2=0 \\ & \mathrm{y}=+4\end{aligned}$
