Both solutions have equal volumes of 30 mL. Which solution is more diluted?

• Solution X

• Solution Y

The amount of solute actually dissolved in a given amount of solvent.

• dilution

• saturated solution

• supersaturated mixture

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

• supersaturated

• diluted

• saturated

• unsaturated

The amount of substance (i.e. solid) dissolved in a another substance (i.e. liquid) is called the ______ of solid in liquid.

• dilute

• concentration

• volume

When you __________ a solution, you make it less concentrated. This can be done by adding more solvent.

• concentrate

• dilute

• stir

• mix

What happens to the concentration of a solution when more solute is added without changing the volume of the solvent?

• It decreases

• It remains the same

• It becomes zero

Which of the following is a method to dilute a concentrated solution?
