The Properties of Mixtures: Types of Solutions Lecture 16

Mixtures everywhere. There are a lot of living mixtures.

Substances with similar type of intermolecular forces dissolve in each other. Like dissolves like. Similia similibus solvuntur .

Solubility (S) is the maximum amount of solute that dissolves in a fixed quantity of a particular solvent at a specified temperature, given the excess solute is present.

Saturated solution

Solutions can be dilute and concentrated. These are relative notions.

Intermolecular forces in solutions Ion-dipole; Hydrogen bonding; Dipole-dipole; Ion — induced dipole. Dipole — induced dipole. Dispersion (London).
