Chapter 9

Solutions

A solution is a mixture of a solute (the substance of which there is less) and a
solvent (that of which there is more). Generally, problems dealing with solutions
tend to focus on a few key areas. This chapter will focus on understanding
solubility, as well as what factors, both external (temperature and pressure) and
internal (nature of the solute and solvent) affect it. It will also deal with some
specific reactions between solutions and how addition of a solute changes the
freezing point and melting point of a solution (colligative properties).
