  3. Bleach - Wikipedia

    en.wikipedia.org/wiki/Bleach

    The grade of chlorine-based bleaches is often expressed as percent active chlorine. One gram of 100% active chlorine bleach has the same bleaching power as one gram of elemental chlorine. The most common chlorine-based bleaches are: Sodium hypochlorite (NaClO), usually as a 3–6% solution in water, usually called "liquid bleach" or just "bleach".

  4. Chlorine production - Wikipedia

    en.wikipedia.org/wiki/Chlorine_production

    Chlorine can be manufactured by the electrolysis of a sodium chloride solution , which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2). These two products, as well as chlorine itself, are highly reactive.

  5. Trichloroisocyanuric acid - Wikipedia

    en.wikipedia.org/wiki/Trichloroisocyanuric_acid

    Trichloroisocyanuric acid is an organic compound with the formula (CONCl) 3.It is used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis. [1] [2] [3] This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use.

    Swimming pools using chlorine have been found to contain trihalomethanes, although generally they are below current EU standard for drinking water (100 micrograms per litre). [4] Concentrations of trihalomethanes (mainly chloroform ) of up to 0.43 ppm have been measured. [ 5 ]

  7. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Chlorine is a strong oxidant that rapidly kills many harmful micro-organisms. Because chlorine is a toxic gas, there is a danger of a release associated with its use. 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 ...

  8. Calcium hypochlorite - Wikipedia

    en.wikipedia.org/wiki/Calcium_hypochlorite

    It strongly smells of chlorine, owing to its slow decomposition in moist air. This compound is relatively stable as a solid and solution and has greater available chlorine than sodium hypochlorite. [1] "Pure" samples have 99.2% active chlorine. Given common industrial purity, an active chlorine content of 65-70% is typical. [2]

  9. Chlorine-releasing compounds - Wikipedia

    en.wikipedia.org/wiki/Chlorine-releasing_compounds

    Chlorine is a respiratory irritant that attacks mucous membranes and burns the skin. As little as 3.53 ppm can be detected as an odor, and 1000 ppm is likely to be fatal after a few deep breaths. Exposure to chlorine has been limited to 0.5 ppm (8-hour time-weighted average—38-hour week) by the U.S. OSHA. [9]
