"Downward displacement of air" is a method of collection of HCl gas.
In the purification of NaCl, impure solution is saturated with HCl gas. The principle involved is
Describe an experiment to prove the following: (i) HCl gas is heavier than air. (ii) HCl gas is highly soluble in water. (iii) HCl gas contains the element chlorine.
