Question

List the raw materials required and the method of manufacture of bleaching powder. Write the equation for the reaction involved.

Answer 1

Answer:

slaked lime and chlorine

Explanation:

Ca(OH)2+Cl2=CaOCl2+H2O

Answer 2

Answer:

• Calcium hydroxide and chlorine are used as the raw materials in the bleaching powder preparation.
• The chemical reaction in between chlorine and slaked lime to produce bleaching powder along with water.

The balanced chemical reaction is as followed below:

                                $\mathrm{Cl}_{2}(g)+\mathrm{Ca}(\mathrm{OH})_{2}(a q) \rightarrow {CaOCl}_{2}(a q)+\mathrm{H}_{2} \mathrm{O}(l)$

Properties of bleaching powder:

• It is yellowish white powder with chlorine smell.
• And it is Soluble in water.
• It is Insoluble in lime water.
• It has an auto oxidation property.
