Percent active chlorine values have now virtually replaced the older system of chlorometric degrees: 1% active chlorine is equivalent to 3.16 °Cl. Taking the (reasonable) assumption that all active chlorine present in a liquid bleach is in the form of hypochlorite ions, 1% active chlorine is equivalent to 0.141 mol/kg ClO − (0.141 mol/L if ...
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".

Percent active chlorine in these materials ranges from 20% for bleaching powder to 70% for HTH. Potassium hypochlorite, KOCl. This was the first chlorine-based bleaching agent, which became available around 1785 under the name Eau de Javel or "Javel water". It is no longer commonly used, having been superseded by the cheaper sodium analog.
The Electro-Alkaline Company [16] was founded on May 3, 1913, as the first commercial-scale liquid bleach manufacturer in the United States. Archibald Taft, a banker; Edward Hughes, a purveyor of wood and coal; Charles Husband, a bookkeeper; Rufus Myers, a lawyer; and William Hussey, a miner, each invested $100 to set up a factory on the east side of San Francisco Bay.

It was estimated that a commercial-size swimming pool of 220,000 gallons would contain about 20 gallons of urine, equivalent to about 2 gallons of urine in a typical residential pool. [ 6 ] Pathogenic contaminants are of greatest concern in swimming pools as they have been associated with numerous recreational water illnesses (RWIs). [ 7 ]
If it's 1% active chlorine that means it has the equivalent of 10 grams chlorine per litre (or per km, I don't know which is the official definition). Ten grams of chlorine is about 0.141 moles. A mole of Cl 2 is equivalent to a mole of ClO −, so the article is correct. Eric Kvaalen 10:19, 6 November 2014 (UTC)
Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two. Chlorine has the electron configuration [Ne]3s 2 3p 5, with the seven electrons in the third and outermost shell acting as its valence ...
