反応性
Hypochlorous acid is a weak acid where the chlorine
atom is in the ＋1 oxidation state and has the
formula HClO. It forms when Cl2 dissolves in water.
It cannot be isolated in pure form due to rapid equilibration
with its precursor. Addition of chlorine to water gives both hydrochloric acid (HCl) and hypochlorous acid:
Cl2＋H2O→HClO＋HCl
