Question

Match the list 1 (mixtures) with list 2 (solution used for separation).

Answer 1

$\left(A\right)$ Ammonical $CuCl$ has great affinity for $CO$. Thus the carbon mono oxide get absorbed in $CuCl$ while $N_2$ does not react.

$\left(B\right)$ $N_2$ is insoluble in water while $O_2$ is slightly soluble.

$\left(C\right)$ $N{H}_3$ reacts with $H_{2}S{O}_4$ by acid-base neutralisation reaction forming ammonium sulphate as the salt. $N_2$ does not react.

$\left(D\right)$ The aqueous solubility of $P{H}_3$ is slight while $N{H}_3$ forms ammonium hydroxide in water.
