Answer
HCl gas present in the flask dissolves in water due to high solubility, creating a partial vacuum in the flask. The outside pressure being higher pushes the blue litmus solution up the jet tube which emerges out at the end of the tube as red fountain. Hence, the inference is that the HCl gas is highly soluble in water and acidic in nature.
