What acid is produced when chlorine gas contacts mucous membranes?

When chlorine gas comes into contact with mucous membranes, it reacts with the moisture (water) present to form hydrochloric acid. This reaction is significant because hydrochloric acid is a strong acid that can cause severe irritation and damage to tissues.

In the presence of water, chlorine gas undergoes hydrolysis, resulting in the formation of hydrochloric acid and hypochlorous acid. This is particularly relevant in medical emergencies, as understanding the chemical interactions of chlorine is crucial for managing exposures and the potential effects on the body.

The other acids listed, such as sulfuric acid and boric acid, do not relate directly to chlorine gas exposure. Sulfuric acid is a different compound with distinct properties and does not form when chlorine gas is involved. Similarly, boric acid is typically associated with other reactions and would not be produced from chlorine. The mention of a strong alkali also does not apply here, as the reaction with chlorine yields acidic products rather than alkaline ones. Understanding these chemical interactions is key for emergency medical responders in handling chlorine exposure cases efficiently and safely.
