Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [40] taking 0.2–2 mg of sodium hypochlorite per liter of water. [41] Dilute solutions (50 ppm to 1.5%) are found in disinfecting sprays and wipes used on hard surfaces. [42] [43]
The hypochlorite can be in the form of a powder or a liquid such as chlorine bleach (solution of sodium hypochlorite or calcium hypochlorite in water). Water that is being shock chlorinated should not be swum in or drunk until the sodium hypochlorite count in the water goes down to three parts per million (ppm) or until the calcium hypochlorite ...
Calcium hypochlorite, Ca(OCl) 2. [20] This product, known as "bleaching powder" or "chlorinated lime", it is used in many of the same applications as sodium hypochlorite, but is more stable and contains more available chlorine. It is usually marketed as a white powder that contains, besides the hypochlorite, also calcium hydroxide Ca(OH)
Calcium hypochlorite can also be used in the haloform reaction to manufacture chloroform. [8] Calcium hypochlorite can be used to oxidize thiol and sulfide byproducts in organic synthesis and thereby reduce their odour and make them safe to dispose of. [9] The reagent used in organic chemistry is similar to the sanitizer at ~70% purity. [10]
Common bleach including calcium hypochlorite (Ca[OCl] 2) and sodium hypochlorite (NaOCl) are common, well-researched, low-cost oxidizers. Chlorine bleach tablets give a more stable platform for disinfecting the water than liquid bleach as the liquid version tends to degrade with age and give unregulated results unless assays are carried out ...
Application of mixed-oxidant solution for disinfecting water has several advantages compared to other methods, such as sodium hypochlorite bleach and calcium hypochlorite. The disinfecting effect of applying mixed oxidant is more efficacious and has fewer safety concerns than other methods, such as chlorination and ozonation. It is generally ...
This problem is avoided by the use of sodium hypochlorite, which is a relatively inexpensive solution used in household bleach that releases free chlorine when dissolved in water. Chlorine solutions can be generated on site by electrolyzing common salt solutions. A solid form, calcium hypochlorite, releases chlorine on contact with water ...
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 ...
