Question

1. Normal freezing point of a solvent is 15°C. A 0-5
molal solution of urea in the above solvent causes
a freezing point depression of two degrees. Calcu-
late the molal depression constant.​

Answer 1

Answer:

We have,

ΔT

f

=iK

f

m

0.256=i∗5.12∗0.1

i=0.5

since, the value of i is less than 1, and acetic acid is solute,

Hence, we can say that acetic acid is doubly associated
