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.
