Question

Give the chemical name & formula of chloride of lime. what happens when it is exposed to air. Write Chemical equation.

Answer 1

The definition of chloride of lime is a white powder used for disinfecting which is made by treating slaked lime with chlorine. An example of a chloride of lime is a substance used for commercial bleach and in laundering as a disinfectant.

Formula:$Ca(OCl{)}_2$

Chemical name:Calcium Hypochorite

Chloride of lime should store well in air tight sealed containers, but the natural presence of carbon dioxide in air causes decomposition, forming chlorine gas and calcium carbonate

$CaOC{l}_2+C{O}_2\to CaC{O}_3+C{l}_2$

Hence chloride of lime gradually lose it chlorine when exposed to air.
