Q. The freezing point of equimolal aqueous solutions will be highest for

KEAMKEAM 2017Solutions

Solution:

For Equimolal Solution

(i) Collegative property means $\propto$ number. of particles after dissociation or association.

Less be the number of particles, more be the melting point and more be the number of particles, more lower be the melting in melting point.

(ii) As number of particles for $D$ -fructose is minimum

($\because$ It will not dissociates). The lowering in freezing point is least i.e has highest freezing point.
