Which of the following will have the highest f.pt. at one atmosphere?

Options

A. 0.1 M NaCl solution
B. 0.1 M sugar solution
C. 0.1 M `BaCl_2` solution
D. 0.1 M `FeCl_3`, solution

Answer

B

Explanation

For the same concentration of different solvent any colligative property `prop i`
For NaCl, i = 2, sugar solution, i = 1
`BaCl_2, i = 3, FeCl_3, i 4`. Thus, for sugar solution depression in freezing point is minimum i.e., highest freezing point
