What is the formula of chlorine water?

Chlorine water, also known as chlorine solution or chlorine bleach, is a solution of chlorine gas (Cl2) dissolved in water. The formula for chlorine gas is Cl2. When it dissolves in water, it forms an equilibrium with hypochlorous acid (HClO) and hydrochloric acid (HCl), which are responsible for its disinfecting properties.

The balanced chemical equation for the dissolution of chlorine gas in water is:

Cl2 (g) + H2O (l) ⇌ HClO (aq) + HCl (aq)

In this equation, (g) represents a gaseous state, (l) represents a liquid state, and (aq) represents an aqueous solution. Chlorine water contains a mixture of these compounds in equilibrium, with hypochlorous acid being the predominant species responsible for the disinfecting action.
