उत्तर
An aqueous solution of ammonia is prepared by dissolving ammonia in water. Ammonia is highly soluble in water.
The funnel arrangement is used to prepare aqueous solution of ammonia. In this method, ammonia gas is introduced through a funnel tube where the rate of dissolution of ammonia is faster than it is produced. This creates a partial vacuum, in delivery tube, resulting in low pressure. Thus, water is forced in to equalise the pressure. To overcome this problem of back suction, the funnel is attached to outer end of the delivery tube and mouth of funnel just dips into the water in the trough.
Two advantages of this method :
(i) Prevents back suction of water into the fla sk.
(ii ) Provides a larger surface area for the absorption of the gas.
Key: Ammonia is highly soluble in water.
