Chemistry: Boiling point elevation and freezing point depression

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. An example of this would be the addition of salt to an icy sidewalk. The solute (salt) reduces the freezing point of the ice, which allows the ice to melt at a lower temperature.​

Chemistry

Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

Mixtures and solutions

The air you are (hopefully) breathing is a mixture of nitrogen and oxygen gases. We could also think of it as a solution of oxygen gas in nitrogen gas. In this section we will be learning about different types of mixtures, how to calculate concentration, and colligative properties.
