Understand Fountain experiment of ammonia. Click on the Link to Watch the VIDEO explanation: Watch Video
The apparatus required for the interesting experiment is arranged as shown here. Red litmus solution is taken into lower flask while the upper one contains ammonia gas. When air is blown into lower flask high pressure is created in the flask due to high pressure the red litmus solution is sucked into the upper flask then red litmus solution's colour immediately changed into blue colour and comes out in the form of Fountain through the jet tube. Ammonia is basic in nature and is highly soluble in water that is the reason the colour of solution changes to blue.
