Bleach decomposition
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 … 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).

WebApr 1, 1997 · Studies have led to an understanding of how chlorate ion (ClO 3 –) formation in the pH 6–13 region from decomposing bleach is affected by pH, temperature, NaOCl … 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.
Most industrial and household bleaches belong to three broad classes: • Chlorine-based bleaches, whose active agent is chlorine, usually from the decomposition of some chlorine compound like hypochlorite or chloramine. • Peroxide-based bleaches, whose active agent is oxygen, almost always from the decomposition of a peroxide compound like hydrogen peroxide. Webbleach, solid or liquid chemical used to whiten or remove the natural colour of fibres, yarns, other textiles, and paper. In textile finishing, the bleaching process is used to produce white cloth, to prepare fabrics for other …
WebSuch decomposition can generate species such as hypochlorous acid (HOCl) that can then feed additional reactions with other cleaning products. Bleach decomposition depends on storage conditions and use; it … WebDec 11, 2024 · The reactant used is household bleach, which contains 5 to 6% of NaClO. The decomposition can be stated in this following equation: 2 ClO- (aq) –> 2 Cl- (aq) + O2 (g) To measure the rate of decomposition, a catalyst is needed to fasten the reaction. A suitable catalyst is Co2O3, which is produced from mixing Co (NO3)2 and bleach.
WebThe issue is not simply one of lost product and higher usage, of equal concern are the sodium chlorate and oxygen produced in the decomposition reaction. 12.5% UltraChlor is an optimum concentration in that its degradation rate is low enough to allow it to have a thirty-day useful shelf life under a variety of storage conditions while it ...
WebSep 22, 2024 · You have outlined the principal decomposition path of hypochlorite in the question. Chlorate in itself is rather stable under ambient conditions and would probably not decompose. The greatest danger is if the bleach solution is no longer alkaline.
