Chlorine bleaches by the process of oxidation. It needs moisture for its bleaching action.
Chlorine bleaches by the process of oxidation. It needs moisture for its bleaching action.
Chlorine reacts with water to form hydrochloric and hypochlorous acids.
$Cl_2+ H_2 O \longrightarrow HCl + HClO$
Hypochlorous acid is unstable, and it easily dissociates to form nascent oxygen.
$HClO \longrightarrow HCl +[ O ]$
Nascent oxygen is a more powerful oxidising agent. Its formation is responsible for the bleaching nature of chlorine in the presence of moisture.
