Correct the following statement:
Hydrochloric acid is prepared in the laboratory by passing hydrogen chloride directly through water.

उत्तर
Hydrochloric acid is not prepared directly dissolving hydrochloride gas in water because it may lead to back suction. When the delivery tube carrying HCI gas is directly immersed in water, the reverse rise of water in delivery tube is known as back suction.
To prepare hydrochloric acid from hydrogen gas, it is essential to avoid back suction and it is done by using 'inverted funnel arrangement'.
