Chapter 9: Physical Properties of Solutions

Solution that contains the maximum amount of solute that can be dissolved.

• unsaturated solution

• supersaturated solution

• saturated solution

When materials combine to form a mixture, they

• A. keep their original properties.
• B. react to form a new substance with new properties.
• C. combine in a specific ratio.
• D. always change their physical state.

How does a solution become supersaturated?

• dissolve lots of solute in it.
• dissolve a little solute in it. 
• dissolve more solute than you should be able to. 
• dissolve a solvent in it. 

A small amount of NaCl is dissolved in water to make a solution. In this solution

• water is the precipitate

• water is the solute

• NaCl is the solvent

• NaCl is the solute

Solution where more solute can still be dissolved at the given temperature. 

• Saturated
• Unsaturated
• Supersaturated
• Homogeneous solution

What happens to the concentration of saltwater if you left it boiling on a stove without a lid?

• It becomes diluted as the water evaporates

• It becomes more concentrated as the water evaporates.

• The concentration does not change.

The substance being dissolved is called the ________
