Discusses the importance of solvent extraction, provides examples, looks at the importance of appropriate solvent selection, describes the conditions needed for extraction, and explains some of the methods used.

Students identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves.

Students will use the terms solute and solvent in describing a solution. They will sketch a solution at the particle level and design and conduct an experiment to determine the factors (e.g., agitation, particle size, temperature)...

Understand how temperature, pressure, and the presence of other solutes affect the solubility of solutes in solvents.
