  2. Chemical drain cleaners - Wikipedia

    en.wikipedia.org/wiki/Chemical_drain_cleaners

    Drain cleaners usually contain a strong base such as sodium hydroxide that decomposes hair and converts fats into water-soluble products. The reaction is exothermic, releasing heat to soften the fats. Drain cleaners can also contain aluminum, which reacts with sodium hydroxide to produce bubbles of hydrogen gas that help to break up the clog. [11]

  3. Sodium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Sodium_hypochlorite

    Sodium hypochlorite is an alkaline inorganic chemical compound with the formula Na O Cl (also written as NaClO). It is commonly known in a dilute aqueous solution as bleach or chlorine bleach. [4] It is the sodium salt of hypochlorous acid, consisting of sodium cations (Na +) and hypochlorite anions (− OCl, also written as OCl − and ClO −

  4. Shock chlorination - Wikipedia

    en.wikipedia.org/wiki/Shock_chlorination

    Shock chlorination is a process used in many swimming pools, water wells, springs, and other water sources to reduce the bacterial and algal residue in the water. Shock chlorination is performed by mixing a large amount of sodium hypochlorite, which can be in the form of a powder or a liquid such as chlorine bleach, into the water.

  5. Chlorine-releasing compounds - Wikipedia

    en.wikipedia.org/wiki/Chlorine-releasing_compounds

    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) 2 ("lime") and calcium chloride CaCl 2. [21]

  6. Water chlorination - Wikipedia

    en.wikipedia.org/wiki/Water_chlorination

    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 ...

  7. Salt water chlorination - Wikipedia

    en.wikipedia.org/wiki/Salt_water_chlorination

    Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...

  8. Hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Hypochlorite

    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 ...

  9. Dakin's solution - Wikipedia

    en.wikipedia.org/wiki/Dakin's_solution

    Dakin's original solution contained sodium hypochlorite (0.4% to 0.5%), prepared by treating calcium hypochlorite with sodium carbonate ("washing soda"). The solution left after removal of the insoluble calcium carbonate still contained some soda. [7] Boric acid (4%) was then added as a buffering agent to maintain a pH of between 9 and 10.
