Question

write the name and chemical formula of the product formed by the action of chlorine on slaked lime

Answer 1

slaked lime is Ca(OH)2 not CaO

the reaction is

Ca(OH)2+Cl2----> CaOCl2+H2O

Answer 2

Answer: The chemical name of bleaching powder is calcium oxychloride and its chemical formula is $CaOCl_2$

Explanation:

The chemical formula for slaked lime is $Ca(OH)_2$ and is named as calcium hydroxide.

Bleaching powder is a white colored compound which is formed by the reaction of slaked line with the released chlorine gas from the electrolysis of brine solution. The chemical formula for this compound is $CaOCl_2$

The chemical equation for the formation of bleaching powder follows:

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

By Stoichiometry of the reaction:

1 mole of slaked lime (calcium hydroxide) reacts with 1 mole of chlorine gas to produce 1 mole of bleaching powder (calcium oxychloride) and 1 mole of water.

Hence, the chemical name of bleaching powder is calcium oxychloride and its chemical formula is $CaOCl_2$
