Question
Answer the following in one or two sentences.
Write the equation relating boiling point elevation to the concentration of the solution.
Solution
The boiling point elevation is directly proportional to the molality of the solution. Thus,
Δ Tb ∝ m
∴ Δ Tb = Kb m
where m is the molality of the solution. The proportionality constant Kb is called the boiling point elevation constant or molal elevation constant or ebullioscopic constant.
