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".
To extend their disinfectant usefulness and persistence in outdoor settings, swimming pools treated with one or more of the inorganic forms of chlorine-releasing compounds can be supplemented with cyanuric acid – a granular stabilizing agent capable of extending the active chlorine residual half-life (t ½) by four to sixfold.

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 It is no longer commonly used, having been superseded by the cheaper sodium analog.
Zinc chloride is an inorganic chemical compound with the formula ZnCl 2 ·nH 2 O, with n ranging from 0 to 4.5, forming hydrates.Zinc chloride, anhydrous and its hydrates, are colorless or white crystalline solids, and are highly soluble in water.

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)
