Properties of a solution that depend only on the ratio of the number of particles of solute and solvent in the solution are known as:

intensive properties

extensive properties

colligative properties

chemical properties

The correct answer is the third option. Properties of a solution that depend only on the ratio of the number of particles of solute and solvent in the solution are known as colligative properties. These set of properties do not depend on the type of species present. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering.

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf
