The boiling point elevation is a state in which the boiling point of the solution will be higher than the boiling point of the solvent. For instance, water has a boiling point of 100° C, it can be elevated by adding salt (solute) to it, in which the boiling point of the water + salt solution will be higher. This simple formula can be used to find the boiling point elevation of various solvents.
The boiling point elevation is completely dependent on the presence of dissolved particles and their number. It is a colligative property of matter. It can be used to measure the degree of dissociation of a solute.
