Percent active chlorine

(重定向自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 same bleaching power as one gram of chlorine. The term "active chlorine" is used because most commercial bleaches contain substantial amounts of chlorine in the form of chloride ions, which have no bleaching properties.
