Question

Which of the following compound is produced on strong heating ?

• A. $NaN{O}_2$
• B. $N{H}_{4}N{O}_3$
• C. $NaN{O}_3$
• D. None of these

Answer 1

The correct option is A $NaN{O}_2$

Sodium nitrite $\left({NaNO}_2\right)$ is formed by strong heating sodium nitrate $\left({NaNO}_3\right)$.

${NaNO}_3\to {NaNO}_2+\frac{1}{2}{O}_2$

(strong heat)

Ammonium nitrate cannot be prepared by strong heating as in such hot conditions it decomposes.

${NH}_4{NO}_3\to N_{2}O+{2H}_{2}O$

(strong heat)

Hence, the right answer is ${NaNO}_2$.
