We dissolve #25*g# mass of the following solutes in equivalent volumes of water. Which solutions will display the GREATEST freezing point depression?
Freezing point depression depends on the NUMBER of particles in solution; therefore, maximum depression is observed for the solute with least molar mass.
And the solute with least molar mass is clearly sodium fluoride:

The freezing point depression depends on the number of solute particles in the solution. Therefore, the solute that dissociates into the greatest number of particles will result in the greatest freezing point depression. Among common solutes, ionic compounds such as sodium chloride (NaCl) and calcium chloride (CaCl2) dissociate into more particles than molecular compounds like glucose (C6H12O6). Therefore, solutions of sodium chloride (NaCl) and calcium chloride (CaCl2) will display the greatest freezing point depression.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
