Answer 2

Answer:

The chemical name of bleaching powder is Calcium oxychloride. Its chemical formula is ${CaOCl_2}$.

When calcium hydroxide is reacts with chlorine it yields bleaching powder.  Its chemical reaction is given below.

$Ca(OH)_2+Cl_2\rightarrow CaOCl_2+H_2O$

Here,

$C_a(OH)_2$ is calcium hydroxide

$Cl_2$ is chlorine

$H_2O$ is water

So, chlorine reacts with calcium hydroxide to form bleaching powder.
