Potassium hypochlorite is a chemical compound with the chemical formula K O Cl, also written as KClO. It is the potassium salt of hypochlorous acid. It consists of potassium cations (K⁺) and hypochlorite anions (⁻OCl). It is used in variable concentrations, often diluted in water solution. Its aqueous solutions are colorless liquids (light yellow when impure) that have a strong chlorine smell. It is used as a biocide and disinfectant.
