Name: (f) the experiment which demonstrates that hydrogen chloride is soluble in water.

Solution
- Fountain experiment demonstrates that hydrogen chloride is soluble in water.
- In this experiment, the very first step is injecting water from the dropper into the flask. The hydrogen chloride gas present in the flask dissolves in presence of water creating a partial vacuum.
- Thereby, the air pressure around the tube causes the water level to rise and squeezes the water into the flask in the form of a fountain which is observed to be red in colour.
- Therefore, the change in colour of the blue litmus solution into the red colour fountain shows the acidic nature of hydrogen chloride gas that has dissolved in water making it acidic.
