Web12 sep. 2024 · The boiling point elevation happens both when the solute is an electrolyte, such as various salts, and a nonelectrolyte. In thermodynamic terms, the origin of the boiling point elevation is entropic and can be explained in terms of the vapor pressure or chemical potential of the solvent. WebThis video is providing the concept of hydrogen bond effect on boiling points of liquid by considering Water and Methanol as an example.
