Vedclass · Answer

(A) When we exhale,the air we breathe out contains a significant amount of $CO_2$ (carbon dioxide).When this $CO_2$ is passed through lime water $(Ca(OH)_2)$,it reacts to form calcium carbonate $(CaCO_3)$,which is an insoluble white precipitate.The chemical reaction is: $Ca(OH)_2 + CO_2 \rightarrow CaCO_3 + H_2O$.This formation of calcium carbonate makes the lime water appear milky.
