Question

Consider the statements for preparation of nitric acid.

i)Conc.$H_{2}S{O}_4$ is non-volatile.

ii)Produce volatile nitric acid.

• A. Only i) is correct
• B. Only ii) is correct
• C. Both i) and ii) are correct and are not related
• D. Both i) and ii) are correct and are related.

Answer 1

The correct option is D

Both i) and ii) are correct and are related.

Nitric acid is obtained by heating a mixture of concentrated sulphuric acid and sodium or potassium nitratr at ${200}^{0}C$.

$KN{O}_3+H_{2}S{O}_4->\underset{\text{Volatile}}{HN{O}_3}+KHS{O}_4$.

They are related as other acid like Conc.$HCl$ are more volatile than $HN{O}_3$.
