50 cm\(^3\) of sulphur (IV) oxide, 800cm\(^3\) of ammonia, 450 cm\(^3\) of hydrogen chloride, 1.0 cm\(^3\)of Carbon(IV) oxide will respectively saturate 1.0 cm\(^3\) of water at 15°C. Which of the following is suitable for demonstrating the fountain experiment?
The fountain experiment is a chemistry demonstration that shows the solubility of a gas in water. In the experiment, a soluble gas like ammonia or hydrogen chloride is placed in a flask and water is injected into the flask. The gas dissolves in the water, which lowers the pressure in the flask and causes water to be sucked in from another source. The fountain experiment demonstrates the highly soluble nature of hydrogen chloride and ammonia gas in water.
