At equal concentrations, would a nonelectrolyte (e. g. glucose) or electrolyte (e. g.NaCl) containing solution have a lower freezing point? Why?

Solution with electrolyte will have a lower freezing point than the solution with non electrolyte.

Explanation:

Depression in freezing point is given by :

Where :

i = van't Hoff factor

= Molal depression constant of solvent

m = molaity of the solution

Let the molality of the glucose and NaCl solution be = m

Molal depression constant of water =

1) The values of van't Hoff factor for glucose is = 1 (non electrolyte)

Depression in freezing point of glucose solution :

2) The values of van't Hoff factor for NaCl is = 2 (electrolyte)

Depression in freezing point of NaCl solution :

1 < 2

Higher the depression in freezing point more will be the lower freezing point of the solution.This means that solution with electrolyte will have a lower freezing point than the solution with non electrolyte.
