$Ca(OH)_2$

Vedclass · Answer

(C) The chemical $A$ is calcium hydroxide,$Ca(OH)_2$,also known as slaked lime.$1$. It is used for water softening to remove temporary hardness by reacting with calcium bicarbonate: $Ca(HCO_3)_2 + Ca(OH)_2 	o 2CaCO_3 \downarrow + 2H_2O$.$2$. It reacts with sodium carbonate $(Na_2CO_3)$ to produce caustic soda $(NaOH)$: $Ca(OH)_2 + Na_2CO_3 	o 2NaOH + CaCO_3$.$3$. When $CO_2$ is passed through lime water $(Ca(OH)_2)$,it turns milky due to the formation of insoluble calcium carbonate: $Ca(OH)_2 + CO_2 	o CaCO_3 \downarrow + H_2O$.

Chemical $A$ is used for water softening to remove temporary hardness. $A$ reacts with $Na_2CO_3$ to generate caustic soda. When $CO_2$ is bubbled through $A$,it turns cloudy. What is the chemical formula of $A$?
