Single Choice

A and B are two gases. A is identified with the glass rod dipped in $$NH_3$$ and $$\mathrm{B}$$ is identified with the glass rod dipped in $$HCl$$. Then A and B are :

A$$\mathrm{H}\mathrm{Cl},\ \mathrm{N}\mathrm{O}_{2}$$
B$$\mathrm{H}\mathrm{Cl},\ \mathrm{N}\mathrm{H}_{3}$$
Correct Answer
C$$\mathrm{N}\mathrm{H}_{3}$$, H$$\mathrm{Cl}$$
D$$\mathrm{N}\mathrm{H}_{3},\ \mathrm{S}\mathrm{O}_{2}$$

Solution

When glass rod dipped in $$NH_3$$, it is $$HCl$$ which reacts to form $$NH_4Cl$$ and when dipped in $$HCl$$, it is $$NH_3$$ which react to form $$NH_4Cl$$.
