Question

WHY is there a difference between how an electrolytes and non electrolytes affect collegiative properties?

Answer 1

Electrolytes provide more solutes to the solution via dissociation; hence, the colligative properties are considerably changed. Nonelectrolytes provide low solute to the solution since there is no dissociation; hence, the colligative properties are not considerably changed.

Answer 2

Colligative properties are dependent upon the number of molecules or ions present in solution. Therefore, 1 mole of Na2SO4 will produce 3 moles of ions and so it will have 3 times as much of an effect as 1 mole of sugar, which is not an electrolyte and can't dissociate to an appreciable extent.
