The experimental depression in freezing point of a dilute solution is 0.025 K. if the van,t hoff factor (i) is 2.0 the calculated depression in freezing point (in K) is

Options

A. 0.00125
B. 0.025
C. 0.0125
D. 0.05

Answer

c

Explanation

Given depression in freezing point of a dilute solution is 0.025 K.
I = 2.0
wan't hoff factor
(i) `= ("observed colligatvie property" ("experimenta"))/("Calculated colligative property")`
`2.0 = (0.25)/("calculated colligative proptery")`
Calculated depression in freezing point = 0.0125 K
