Question

CaOCl2(calcium oxychloride which is actually bleaching power) loses its chlorine content when it is kept exposed to air as it reacts with atmospheric CO2:
CaOCl2+CO2 => CaCO3+ Cl2
Again if Bleaching powder is kept even in an air tight container, will slowly decompose of its own and form calcium chlorate and calcium chloride. The reaction is called auto-oxidation. This will result in decrease in its chlorine contents.
6CaOCl2 Bleaching powder→Ca(ClO3)2 Calcium chlorate+5CaCl2 Calcium chloride

So how can we store bleaching powder, so that it does not lose its chlorine content and thereby the oxidizing property of bleaching powder is also conserved??

Answer 1

Answer:

Bleaching powder can be stored with proper precautions and with rhe help of some chemicals it can be preserved.

The bleaching power which we are using nowadays is not pure bleaching powder.
