Solution

The chemical required in the experiment to show that carbon dioxide gas is released during respiration is potassium hydroxide. Potassium hydroxide absorbs the carbon dioxide produced during the process of respiration and creates a vacuum in the flask.

Hence, the correct answer is option 4.
