Bleach is the generic name for any chemical product that is used industrially or domestically to remove color from (i.e. to whiten) fabric or fiber (in a process called bleaching) or to disinfect after cleaning.
[7] [8] [9] Sodium hypochlorite is most often encountered as a pale greenish-yellow dilute solution referred to as chlorine bleach, which is a household chemical widely used (since the 18th century) as a disinfectant and bleaching agent.
Liquid bleach, often called just bleach, is a common chemical household product that consists of a dilute solution of sodium hypochlorite (NaClO) and other secondary ingredients. It is a chlorine releasing bleaching agent widely used to whiten clothes and remove stains, as a disinfectant to kill germs , and for several other uses.
In chemistry, hypochlorite, or chloroxide is an anion 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] The Cl-O distance in ClO − is 1.69 Å ...
This chlorine-releasing compound is the most common bleaching and disinfection compound. A dilute (3–6%) aqueous solution in water, historically known as Eau de Labarraque or "Labarraque's water", [17] is widely marketed as a household cleaning product, under the name "liquid bleach" or simply "bleach".
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.
Percent active chlorine is a unit of concentration used for hypochlorite-based bleaches.One gram of a 100% active chlorine bleach has the quantitative bleaching capacity as one gram of free chlorine.
Chlorine dioxide also produces 70% fewer halomethanes in the presence of natural organic matter compared to when elemental chlorine or bleach is used. [27] Chlorine dioxide is also superior to chlorine when operating above pH 7, [17]: 4–33 in the presence of ammonia and amines, [28] and for the control of biofilms in water distribution ...
