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 −.
It is the concentration recommended by the U.S. Centers for Disease Control (CDC) as a household disinfectant. [19] In one study, bactericidal effects of sodium hypochlorite solution were observed at concentrations as low as 0.025%, without any tissue toxicity in vivo or in vitro.
Chlorine dioxide has many applications as an oxidizer or disinfectant. [1] Chlorine dioxide can be used for air disinfection [ 33 ] and was the principal agent used in the decontamination of buildings in the United States after the 2001 anthrax attacks . [ 34 ]
A mixed oxidant solution (MOS) is a type of disinfectant that has many uses including disinfecting, sterilizing, and eliminating pathogenic microorganisms in water. [1] An MOS may have advantages such as a higher disinfecting power, stable residual chlorine in water, elimination of biofilm, and safety. [2]
An AA battery in a glass of tap water with salt showing hydrogen produced at the negative terminal. Electrolysed water (also electrolyzed water, EOW, ECA, electrolyzed oxidizing water, electro-activated water, super-oxidized solution or electro-chemically activated water solution) is produced by the electrolysis of ordinary tap water containing dissolved sodium chloride.

In chemistry, hypochlorite, or chloroxide is an oxyanion with the chemical formula ClO −.It combines with a number of cations to form hypochlorite salts. Common examples include sodium hypochlorite (household bleach) and calcium hypochlorite (a component of bleaching powder, swimming pool "chlorine"). [1]
Calcium hypochlorite is an inorganic compound with chemical formula Ca(Cl O) 2, also written as Ca(OCl) 2.It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.
Manual Control Chlorinator for the liquefaction of chlorine for water purification, early 20th century. From Chlorination of Water by Joseph Race, 1918. The first continuous use of chlorine in the United States for disinfection took place in 1908 at Boonton Reservoir (on the Rockaway River), which served as the supply for Jersey City, New ...
