Boiling-point elevation

작성자 Uploader : atom 작성일 Upload Date: 2018-09-12변경일 Update Date: 2018-09-13조회수 View : 551

Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.

ΔTb = Tb - Tbs

ΔTb = m*Kb

ΔTb : temperature increment by boiling point elevation (℃)
Tb : boiling point of solution (℃)
Tbs : boiling point of solvent (℃)
m : molality of the solution (mol/kg)
Kb : ebullioscopic constant (℃/m)
