Question

3.
In the fountain experiment to demonstrate the high solubility of gas in water, dry HCl gas is
filled in the round bottom flask.​

Answer 1

Answer:

look in explanation.

Explanation:

in the fountain experiment, the most major part is played by the fact that due to HCl's high solubility, the HCl gas present readily dissolves in water, creating a vacuum which leads to the indicator being pulled up.

Now, when the vacuum is created, there is danger of the flask imploding.

thus to minimize this risk, a round bottom flask is used so as to create equal pressure on the walls of the flask.
