KEY TAKEAWAYS •
Raoult’s law applies to ideal solutions and relates to the vapor pressure of a solution versus that of a pure solvent.
•
Colligative properties involve properties that change in a solution based on the number of molecules in the solution rather than on the characteristics of the solute.
•
There are a number of ways that the concentration of a solution can be described—based on weight, volume, and number of moles of the substances.
•
Solubility of a substance is based on its polarity, the polarity of the solvent, temperature, and pressure.
•
Colloids are mixtures of larger molecules between 1 nanometer and 1000 nanometers in a substance in another phase or type of phase.
