Show Answer

Answer: (1)

Solution:

(A) van’t Hoff factor, i

$ i=\frac{\text{ Normal molar mass }}{\text{ Abnormal molar mass }} $

(B) $k_f=$ Cryoscopic constant

(C) Solutions with same osmotic pressure are known as isotonic solutions.

(D) Solutions with same composition of vapour over them are called Azeotrope.
