प्रश्न
Hydrogen chloride gas is very soluble in water. It is dissolved in water to prepare hydrochloric acid by using an anti-suction device, as shown in the diagram. Very briefly explain how this device prevents the suction of water into the flask, in which hydrogen chloride gas is produced.

उत्तर
An inverted funnel connected to the HCI gas supply is placed in a beaker in such a way that the rim of the funnel just touches the surface of water in the beaker. HCI gas coming through the delivery tube fills the mouth of the funnel and then dissolves in water. Hence, a low pressure is created and back suction occurs. As a result of it, water level rises in funnel and level of water in the beaker is lowered. Thus, the rim of the funnel loses contact with water and the outside air rushes in through the gap to equalize the pressure on either side of the funnel. The solution falls back into the beaker due to force of gravity.The water level then falls and the funnel drops back to its original position.
