Bleaching power is a mixed salt of hydrochloric acid and hypochlorious acid. It has the formula, `CaOCI_(2).H_(2)O`. It is manuafactured by the action of chlorine on dry slaked lime at `40^(@)C`. There is also a view that bleaching power is a mixture `[Ca(OCI)_(2)+CaCI_(2).Ca(OH)_(2).H_(2)O]`. The amount of chlorine obtained form a sample of bleching power by the treatement with excess of dilute acids or `CO_(2)` is called a available chlorine. A good sample of bleaching power constains `35-38%` of available chlorine. On long standing, it undergoes auto-oxidation and the amount of acvailable chlorine decreases. The estimation of available chlorine is done volumetrically by (a) iodometric method or by (b) aresenite method. In textile industry, the cotton cloth is mainly bleached with the help of bleaching power.
