Vedclass · Answer

(D) Lime water is a solution of calcium hydroxide,$Ca(OH)_2$.When carbon dioxide $(CO_2)$ is passed through lime water,it forms an insoluble precipitate of calcium carbonate $(CaCO_3)$,which turns the solution milky: $Ca(OH)_2 + CO_2 \rightarrow CaCO_3 + H_2O$.Similarly,sulfur dioxide $(SO_2)$ also reacts with lime water to form calcium sulfite $(CaSO_3)$,which is also an insoluble white precipitate,turning the solution milky: $Ca(OH)_2 + SO_2 \rightarrow CaSO_3 + H_2O$.Therefore,both $CO_2$ and $SO_2$ turn lime water milky.
