A concentrated solution can be obtained from a diluted one by:
- Increasing the amount of solvent
- Decreasing the surface area of the solute
- Increasing the amount of solute or decreasing the amount of solvent by heating (correct)
- Decreasing the amount of solute by cooling
What is an unsaturated solution?
What is an unsaturated solution?
- A solution that contains the maximum amount of solute
- A solution that has no solute dissolved
- A solution that contains less solute than its solubility (correct)
- A solution that contains more solute than its solubility

Study Notes
Solution Concentration
- A concentrated solution has a relatively large amount of dissolved solute.
- A dilute solution has a relatively small amount of dissolved solute.
- A concentrated solution can be obtained from a diluted one by increasing the amount of solute or decreasing the amount of solvent by heating.
- A dilute solution can be obtained from a concentrated one by increasing the amount of solvent.
Solution Types
- Solubility is the maximum quantity of solute in a definite amount of solvent at specific conditions.
- An unsaturated solution has a quantity of solute less than its solubility dissolved in a definite amount of solvent at specific conditions.
- A saturated solution contains the maximum amount of solute (equal to its solubility) dissolved in a definite amount of solvent at specific conditions.
- A supersaturated solution contains more than the maximum amount of solute that is capable of being dissolved at a given temperature.
Factors Affecting Dissolving Rate
- Factors that affect the rate of dissolving a solid solute in a liquid solvent are temperature, stirring (shaking), and increasing the surface area of the solute.
- Increasing temperature, stirring (shaking), and increasing the surface area of the solute increase the dissolving rate.
- The solubility of a gaseous solute in a liquid solvent increases by decreasing the temperature and stirring (shaking).
