Home bleach has a pH of 11, so it is mildly irritating to the skin. Concentrated bleaching powder, which contains 10-15% sodium hypochlorite, has a pH of 13. Due to its high pH, it is highly alkaline.
The chlorine, which was produced during previous reactions of the bleaching powder with dilute acids, acts as a bleaching agent. So chlorine in the bleaching powder acts as a real bleaching agent.
How we store the powder?
It must be stored in an airtight container so that it does not come into contact with air. If it is left in the air, it reacts with carbon dioxide to form calcium carbonate and chlorine.
