Question

Products obtained when Conc.$HN{O}_3$ (Nitric acid ) is heated.

• A. $NO$, $H_{2}O$ and some heat.
• B. $N{O}_2$, $H_{2}O$ and $O_2$.
• C. $NO$, $H_{2}O$ and $O_2$.
• D. $NO$, $H_2$ and $O_2$.

Answer 1

The correct option is B

$N{O}_2$, $H_{2}O$ and $O_2$.

When nitric acid is heated it decomposes to give $N{O}_2$, $H_{2}O$ and $O_2$.

$4HN{O}_3⟶2H_{2}O+4N{O}_2+O_2$
