Vedclass · Answer

(D) Crushed egg-shells consist mainly of calcium carbonate $(CaCO_3)$.When an acid,such as hydrochloric acid $(HCl)$,reacts with calcium carbonate,it produces carbon dioxide gas $(CO_2)$.The reaction is: $CaCO_3 + 2HCl \rightarrow CaCl_2 + H_2O + CO_2 \uparrow$.Carbon dioxide gas turns lime water $(Ca(OH)_2)$ milky due to the formation of insoluble calcium carbonate $(CaCO_3)$.Therefore,the solution must contain $HCl$.

$A$ solution reacts with crushed egg-shells to give a gas that turns lime water milky. The solution contains:
