उत्तर
Ammonia is highly soluble in water. This can be demonstrated by Fountain
experiment.
• We take a round bottom flask filled with ammonia gas.
• The flask is closed with a two holed rubber stopper, one for the jet tube and the other for a dropper filled with water.
• The flask is fixed to the stand in an inverted position .
• The free end of the jet tube is dipped into a beaker containing red litmus
solution .
• When the bulb of dropper is pressed, it is observed that red litmus solution rises up and strikes the wall of the flask and spreads in form of fountain, which is blue in colour.
