Question

water + chlorine gas ---> hydochloric acid + oxygen ​

Answer 1

When chlorine gas (Cl2) is added to the water(H2O), it hydrolyzes rapidly to produce hypochlorous acid (HOCl) and the hypochlorous acid will then dissociate into hypochlorite ions (OCl-) and hydrogen ions (H+)

. Because hydrogen ions are produced, the water will become more acidic (the pH of the water will decrease).

Answer 2

Answer:

When hydrogen ions are produce, the water will become more acidic.
