When a solvent contains as much of the solute as it can hold, the solution is said to be

• supersaturated

• diluted

• saturated

• unsaturated

A solution with a large amount of solute is called _________

• dilute

• saturated

• concentrated

• homogeneous

A ratio comparing the amount of solute to the amount of solution.

• concentration

• solution

• mass

• volume
