Learning objectives: I can...

• Classify mixtures as heterogeneous or homogeneous. Explain that solubility can be affected by the nature of the solute and solvent, temperature, and pressure.

• Explain that the rate of solution can be affected by the size of the particles, stirring, temperature, and the amount of solute already dissolved.
