How to make bleaching powder (viranjak churn banane ki vidhi)
bleaching powder hydrated lime (calcium hydroxide) Formed by the reaction of chlorine gas with The chemical equation for this reaction is:
Cl2 + Ca(OH)2 → Ca(OCl)2 + H2O
The process can be summarized in the following steps:
- Hydrated lime is poured into a reactor vessel and water is added to make a slurry.
- Chlorine gas is then introduced into the reactor vessel, and the mixture is stirred to ensure that the chlorine is thoroughly mixed with the lime solution.
- The reaction between chlorine and lime generates heat and thickens the mixture as bleaching powder is formed.
- The reaction is allowed to continue for a specified period of time depending on the desired end product.
- Then the bleaching powder from the solution is filtered and dried.
- The dry powder is sieved to obtain the desired particle size.
It is important to note that bleaching powder production is controlled by the government and any accident or harmful gases This should be done in a safe and controlled environment to avoid the emission of CO.
