Answer:
To show that HCl gas is heavier than air.
A jar is taken in which a burning candle is kept inside. e HCl gas is poured into this jar, which due to its heaviness, flows downwards, displaces the inside air . Loss of air, i.e. oxygen, causes the flame to extinguish, proving the presence of HCl gas.
