The boiling point can be calculated by using the formula for elevation in boiling point. elevation in boiling point is a colligative property which depends on the number of moles of solute. Concept introduction: Boiling point elevation is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The boiling point of solution is higher than that of the pure solvent and is directly proportional to the molality of the solute. Δ T b = T b ( s o l u t i o n ) − T b ( s o l v e n t ) = K b × m where Δ T b is the boiling point elevation, T b ( s o l u t i o n ) is the boiling point of the solution, T b ( s o l v e n t ) is the boiling point of the solvent, K b is the boiling point elevation constant, and m is the molality.

Interpretation Introduction

Interpretation:

The boiling point can be calculated by using the formula for elevation in boiling point. elevation in boiling point is a colligative property which depends on the number of moles of solute.

Concept introduction:

Boiling point elevation is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The boiling point of solution is higher than that of the pure solvent and is directly proportional to the molality of the solute.

$Δ T_{b} = T_{b} (s o l u t i o n) - T_{b} (s o l v e n t) = K_{b} \times m$

where $Δ T_{b}$ is the boiling point elevation, $T_{b} (s o l u t i o n)$ is the boiling point of the solution, $T_{b} (s o l v e n t)$ is the boiling point of the solvent, $K_{b}$ is the boiling point elevation constant, and m is the molality.
