Question
How will the boiling point of a liter of water containing 1 mole of sodium chloride (NaCl) compare with that of a liter of water containing 1 mole of calcium chloride (CaCl2)? Explain your answer.

Look at the formula for boiling point of each.
delta T = i*Kb*molality
Molality is the same for both solution.
Kb is the same for both solution.
There delta T depends upon i, the van't Hoff factor.
i = 2 for NaCl
i = 3 for CaCl2.
