Answer 2

don't change your question now ok this is ur question

I had answer that chlorine acts as a bleaching agent is the presence of HCL

bcz chlorine contains solution of the gas in water so the answer is HCL or we can say.Chlorine reacts with water to form hydrochloric and hypochlorous acids.

Cl2 + H2O ——→ HCl + HClO

Hypochlorous acid is unstable, and it easily dissociates to form nascent oxygen.

HClO ——→ HCl + [O]

Nascent oxygen is a more powerful oxidising agent. Its formation is responsible for the bleaching nature of chlorine in the presence of moisture.
