Hypochlorous acid is an inorganic compound with the chemical formula Cl O H, also written as HClO, HOCl, or ClHO. [2] [3] Its structure is H−O−Cl.It is an acid that forms when chlorine dissolves in water, and itself partially dissociates, forming a hypochlorite anion, ClO −.
The name can also refer to esters of hypochlorous acid, namely organic compounds with a ClO– group covalently bound to the rest of the molecule. The principal example is tert-butyl hypochlorite, which is a useful chlorinating agent. [3] Most hypochlorite salts are handled as aqueous solutions.
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.
Hypochlorous acid acts as a mild antiseptic and anti-inflammatory agent to help kill harmful bacteria and reduce irritation on the skin, says Azadeh Shirazi, M.D., board-certified dermatologist at ...
Other formulations have been developed over time. In 1916, Marcel Daufresne substituted sodium bicarbonate for Dakin's boric acid as buffering agent. [7] [17] This formulation is the basis of current commercial products. [18] The concentration chosen by Dakin (0.5%) was the maximum highest concentration found tolerable to the skin.
Halazone's disinfecting activity is mainly due to the hypochlorous acid (HClO) released by hydrolysis of the chlorine-nitrogen bonds when the product is dissolved in water: [8] (R1)(R2)NCl + H 2 O → HOCl + (R1)(R2)NH. The hypochlorous acid is a powerful oxidizer and chlorinating agent that destroys or denatures many organic compounds.
The quantitative hydrolysis constant (K value) is used to express the bactericidal power of chloramines, which depends on their generating hypochlorous acid in water. It is expressed by the equation below, and is generally in the range 10 −4 to 10 −10 ( 2.8 × 10 −10 for monochloramine):
Inorganic chloramines are produced by the reaction of ammonia and hypochlorous acid or chlorine. An urban legend claims that mixing household bleach (aqueous sodium hypochlorite) with ammonia-based cleaners releases chlorine gas or mustard gas; in reality, the gas produced by the reaction is a mixture of inorganic chloramines.
