$A$ solution of a substance '$X$' is used for testing carbon dioxide. Identify '$X$'. What will be its reaction with carbon dioxide? Write a balanced equation for the reaction.
(N/A) $(i)$ The substance '$X$' is lime water,which is a solution of calcium hydroxide,$Ca(OH)_{2}$.
$(ii)$ When carbon dioxide gas is passed through lime water,it reacts to form calcium carbonate,which is insoluble in water and makes the solution appear milky.
$(iii)$ The balanced chemical equation for the reaction is: $Ca(OH)_{2}(aq) + CO_{2}(g) \rightarrow CaCO_{3}(s) + H_{2}O(l)$.
