When an ammonium salt is warmed with a sodium hydroxide solution, a gas is evolved. State three ways in which you can identify this gas.

List the properties of ammonia that make it
(i) A good refrigerant
(ii) A cleaning agent
(iii) As a source of hydrogen

State your observation for the following cases

(ii) Glass rod dipped in ammonium hydroxide is brought near the mouth of the concentrated hydrochloric acid bottle

The diagram shows a simple arrangement of the fountain experiment:

(i) Name the two gases you have studied which can be used in this experiment

(ii) What is the common properly demonstrated by this experiment

What do you observe when Ammonia is passed over heated lead oxide.

Differentiate between:
Action on indicators or dry ammonia gas and aqueous ammonia

Of the two gases, ammonia and hydrogen chloride, which is denser? Name the method of collection of this gas.

State a relevant reason for the following:
