Question

Relative lowering of vapour pressure is a colligative property because
A. it depends on the concentration of non-electrolyte solute in solution and does not depend on the nature of the solute molecules
B. it depends on number of particle of electrolyte solute insolution and does not depend on the nature of the solute molecules
C. it depends on the concentration of non-electrolyte solute in solution as well as on the nature of the solute molecules
D. depends on the concentration of an electrolyte or non-electrolyte solute in in solution as well as on the nature of solute molecules

Answer 1

Correct Answer - A::B
Relative lowering of vapour pressure is a colligative property because
(i) It does not depend upon nature of solute.
(ii) It depend s upon number of solute particles.
(iii) It depends upon concentration of non-electrolyte solution.
Hence, (a) and (b) are correct.
