HOCl is the chemical formula for hypochlorous acid, a weak acid formed when chlorine dissolves in water. It acts as a bleach and disinfectant.
Hypochlorite ion (OCl⁻): The conjugate base of HOCl, which is more stable and less acidic.
HClO2 (chlorous acid): A stronger acid than hypochlorous acid, formed when chlorine dioxide dissolves in water.
HClO4 (perchloric acid): The strongest among these acids, formed when chlorine tetroxide dissolves in water.
