Chemistry Final Exam Review- Solutions

The amount of solute that can be dissolved in a specific amount of solvent at a given temperature is its

• concentration.

• density.

• dilution.

• solubility.

A solution that contains all of the solute it can hold at a given temperature is

• diluted.

• saturated.

• supersaturated.

• unsaturated.

You can make a solute dissolve more quickly in a solvent by

• adding more solute.

• adding ice.

• heating the solvent.

• removing some solvent.
