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".
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)
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 It is no longer commonly used, having been superseded by the cheaper sodium analog.

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]
The active agent in liquid bleach is sodium hypochlorite, which gives the product a light greenish yellow tinge and its characteristic chlorine smell. [6]Formulations for household use usually contain 8% or less of sodium hypochlorite by weight, although more concentrated solutions of up to 50% are available for industrial use. [7]
