Boiling-point elevation is the phenomenon whereby the difference in boiling point of a pure liquid (a solvent) compared to when a non-volatile solute is added to that solvent, this usually results in a pure solvent having a lower temperature than its solution. The boiling point can be measured accurately using an ebullioscope.

Article body

- will be adding citation (colligative properties) at the explanation section for the definition of colligative properties

- will be changing title "The equation for calculations at dilute concentration" to "Equations for calculating Boiling Point Elevation"

- will be changing the image/diagram from LibreTexts Chemistry

- will be changing the equation from LibreTexts Chemistry

- at "Uses", Together with the formula above, the boiling-point elevation can in principle be used to measure the degree of dissociation or the molar mass of the solute. This kind of measurement is called ebullioscopy (Latin-Greek "boiling-viewing"). However, avoiding superheating would be challenging. Therefore, ΔT_b would be hard to measure precisely even though superheating was partly overcome by the invention of the Beckmann thermometer. Since the freezing point is often easier to measure with precision, cryoscopy is used more often.
