$iii$. In pure form,its $pH$ is neutral.
$iv$. It is the most active inorganic compound.

Match the following columns:

Column-$I$	Column-$II$
$P$. Cohesion	$I$. Water molecules are attracted to each other more in the liquid phase than in the gaseous phase.
$Q$. Adhesion	$II$. Attraction of water molecules to polar surfaces.
$R$. Surface Tension	$III$. Mutual attraction between water molecules.
