Because $NH_3$ reacts with $H_2SO_4$,$P_2O_5$,and $CaCl_2$.

Vedclass · Answer

(D) $NH_3$ is a Lewis base. $H_2SO_4$ is an acid,$P_2O_5$ is an acidic oxide,and $CaCl_2$ forms an adduct with $NH_3$. $NH_3$ reacts with $H_2SO_4$ to form $(NH_4)_2SO_4$. $NH_3$ reacts with $P_2O_5$ to form ammonium phosphates. $NH_3$ reacts with $CaCl_2$ to form an addition compound $CaCl_2 \cdot 8NH_3$. Therefore,these substances cannot be used to dry $NH_3$.

Why $NH_3$ cannot be dried by $H_2SO_4$,$P_2O_5$,and $CaCl_2$?
