In the adsorption of acetic acid by charcoal why are the flasks stopperd?

This allows for better control of the experiment, ensuring that the adsorption process occurs within the enclosed flask and the concentration of acetic acid is maintained.
What reacts readily with acids such as hydrochloric?
Small amounts of chlorine gas can be made in the laboratory by putting concentrated hydrochloric acid in a flask with a side arm and rubber tubing attached.
