Asked by | 05 Aug, 2011, 12:00: AM
answered-by-expert Expert Answer
Bleaching Powder is made by the action of chlorine gas on calcium hydroxide, the reaction being essentially:
     2Ca(OH)2 +2Cl2--->Ca(OCl)2+CaCl2+2H2O
The real bleaching agent in bleaching powder is chlorine which is available for oxidation.
bleaching powder contains 15-25% of calcium hydroxide and about only 35 % of chlorine is available for oxidation.
