Mixtures, solvents, and solutions
A few definitions
Definitions: Examples:
• Mixture: when two or more different substances are mixed
together but do not combine chemically to form a new
compound.
• Homogeneous mixture: a mixture that is uniform throughout
and has only one phase (e.g. liquid).
• Heterogeneous mixture: a mixture that is separated in
different regions or phases that have different compositions
or properties.
• Solution: homogeneous mixture with one major component
and one or several minor components.
• Solvent: the major component in a solution.
• Solute: a minor component in a solution.
• Dissolution: the process by which a compound is dissolved by
a solvent to become a solute
