What happens when a solution becomes saturated?
More solute dissolves
No more solute can dissolve
The solution evaporates
The solvent changes color
How do you compare the solubility of different solutes?
By checking how fast they dissolve
By measuring how much solute dissolves in a known amount of solvent
By observing the color of the solution
By heating the solvent
What does temperature generally do to the solubility of most solutes?

They break down
A concentrated solution is (a) .
What is the term for a substance that does not dissolve in water?
Saturated
Soluble
Insoluble
Concentrated
What is an example of an insoluble substance? (a)
Hot water dissolves more solute than (a)
Match the following statements about soluble solids in water.
The solid will stop dissolving
If you keep adding a soluble solid to water after it becomes saturated, it will stop dissolving.
The solution will become more concentrated
As more solid is added, the solution will become more concentrated.
The solid will continue to dissolve
The solid will continue to dissolve until saturation is reached.
The water will evaporate
Excess solid may lead to evaporation of water.
What is a concentrated solution?
A solution with a small amount of solute
A solution with a large amount of solute
A solution with no solute
A solution that is saturated
What is a dilute solution?
A solution with a small amount of solute compared to the solvent
A solution with a large amount of solute
A solution where no solute can dissolve
A solution that evaporates quickly
What happens to the concentration of a solution if more solute is added to a fixed amount of solvent? The concentration (a) .
Which of the following describes a dilute solution?
A solution with a large quantity of solute
A solution with very little solute compared to solvent
A solution where solubility has reached its limit
A solution where no solute can be added
How can you turn a concentrated solution into a dilute solution?
Add more solute
Heat the solution
Add more solvent
Freeze the solution
What is the term for a solution that has reached its maximum solute capacity?
Concentrated solution
Dilute solution
Saturated solution
Insoluble solution
Which of the following factors does NOT affect solubility?
