Question

How can we derive the increase in boiling point temperature as a function of solute molar tion?

a) Raoult's law
b) Henry's law
c) Clausius–Clapeyron equation
d) Van't Hoff factor

Answer 1

The increase in boiling point of a solution is calculated with the formula
`ΔT = i × Kb × m` where
`ΔT` is the boiling point elevation i is the van't Hoff factor, Kb is the boiling point elevation constant, and m is the molality.

Step-by-step explanation:

The increase in boiling point temperature of a solution compared to the pure solvent can be derived using the boiling point elevation expression which includes the van't Hoff factor (i). The boiling point elevation
`ΔT` is given by the formula
`ΔT = i × Kb × m` where
`ΔT` is the increase in boiling point Kb is the boiling point elevation constant and m is the molality of the solution.

The van't Hoff factor, i represents the number of particles a solute forms in solution and is crucial for calculating the correct boiling point elevation, particularly for ionic compounds that dissociate into multiple particles.
