which of the foll will have lowest freezing point?

0.10 M K2SO4

0.10M NaCl

0.10 M UREA

0.10 M GLUCOSE

Depression in freezing point = iCRT

 

Thus, depression is directly proportional to vont hoff factor for same molarty,

Highest vont hoff factor is for K2SO4.

 

Lowest F.P. will be of K2SO4 solution.
