Vedclass · Answer

(D) $H_2SO_4$ is a strong acid and a dehydrating agent. To dry a substance,the drying agent must not react with it. $CaO$ is a basic oxide and will react with $H_2SO_4$ to form $CaSO_4$ and $H_2O$. $P_2O_5$ is an acidic oxide but it reacts with $H_2SO_4$ to form phosphoric acid and sulfur trioxide. $CaCl_2$ also reacts with $H_2SO_4$ to form $HCl$ gas. Therefore,none of the given substances can be used to dry $H_2SO_4$.
