Boiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases.

Moore, Justin Shorb, Xavier Prat-Resina, Tim Wendorff, & Adam Hahn. It is well known that boiling point depends on temperature. Most know that water boils at 100 degrees Celsius.
Jan 23, 2023 · Boiling points are influenced by intermolecular forces, which depend on the polarity, size, and shape of the molecules. In this LibreTexts module, you will learn how to predict and explain the boiling points of different substances using the concepts of molecular structure and intermolecular forces. You will also explore some examples and applications of boiling points in chemistry.
Jun 30, 2023 · The melting and boiling points increase down the group because of the van der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Aug 9, 2020 · Information on the properties of common solvents used in organic chemistry including boiling points, solubility, density, dielectric constants, and flash points
Jul 19, 2022 · Both the boiling point elevation and the freezing point depression are related to the molality of the solution. Looking at the formula for the boiling point elevation and freezing point depression, we see similarities between the two. The equation used to calculate the increase in the boiling point is: ΔTb = kb ⋅ m ⋅ i.
Jun 30, 2023 · Both the melting and boiling points decrease down the group. When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond.
