2. Percent active chlorine - Wikipedia

   en.wikipedia.org/wiki/Percent_active_chlorine

   Percent active chlorine is a unit of concentration used for hypochlorite-based bleaches. One gram of a 100% active chlorine bleach has the quantitative bleaching capacity as one gram of free chlorine. The term "active chlorine" is used because most commercial bleaches also contain chlorine in the form of chloride ions, which have no bleaching ...
