Bleach formation equation
WebBleach Science. Bleaches. Bleaching agents are materials that lighten or whiten a substrate (for example a fabric or hard surface) through a chemical reaction. They are used for textile and paper and pulp bleaching as well as for home laundering. Bleaching usually involves either oxidative or reductive reactions that decompose stains and soils. Sodium hypochlorite, commonly known in a dilute solution as (chlorine) bleach, is an inorganic chemical compound with the formula NaOCl (or NaClO), comprising a sodium cation (Na ) and a hypochlorite anion (OCl or ClO ). It may also be viewed as the sodium salt of hypochlorous acid. The anhydrous compound … See more Stability of the solid Anhydrous sodium hypochlorite can be prepared but, like many hypochlorites, it is highly unstable and decomposes explosively on heating or friction. The decomposition is … See more Household bleach sold for use in laundering clothes is a 3–8% solution of sodium hypochlorite at the time of manufacture. Strength varies from one formulation to another and gradually decreases with long storage. Sodium hydroxide is usually added in small … See more It is estimated that there are about 3,300 accidents needing hospital treatment caused by sodium hypochlorite solutions each year in British homes (RoSPA, 2002). Oxidation and corrosion Sodium … See more • Calcium hypochlorite Ca(OCl) 2 ("bleaching powder") • Potassium hypochlorite KOCl (the original "Javel water") See more Chlorination of soda Potassium hypochlorite was first produced in 1789 by Claude Louis Berthollet in his laboratory on the Quai de Javel in Paris, France, by passing See more Bleaching Household bleach is, in general, a solution containing 3–8% sodium hypochlorite, by weight, and 0.01–0.05% sodium hydroxide; the sodium hydroxide is used to slow the decomposition of sodium hypochlorite into sodium chloride See more In spite of its strong biocidal action, sodium hypochlorite per se has limited environmental impact, since the hypochlorite ion rapidly degrades before it can be absorbed by living beings. However, one major concern arising from sodium … See more
