Relative lowering of vapour pressure is a colligative property because _____________.

(i) It depends on the concentration of a non-electrolyte solute in a solution and does not depend on the nature of the solute molecules.

(ii) It depends on a number of particles of electrolyte solute in a solution and does not depend on the nature of the solute particles.

(iii) It depends on the concentration of a non-electrolyte solute in solution as well as on the nature of the solute molecules.

(iv) It depends on the concentration of an electrolyte or nonelectrolyte solute in solution as well as on the nature of solute molecules.

Answers (1)
