We can obtain a fountain of ammonia gas. (Text Book)

Ans. We can obtain a fountain of ammonia gas in the following manner.

1.     Ammonia gas is highly soluble in water. A test tube is filled with ammonia gas.

2.     A Jet Tube is fixed with test tube using a rubber cork.

3.     Red litmus solution is taken in the beaker.

4.     The test tube is fixed to a stand and the open end of the jet tube is inserted in the litmus solution.

5.     Red litmus solution is sucked in the test tube, since ammonia is a colourless basic gas and hence it turns red litmus solution blue, hence blue fountain is formed.
