You can make a solute dissolve more quickly in a solvent by

• adding more solute.

• adding ice.

• heating the solvent.

• removing some solvent.

A solution that contains all of the solute it can hold at a given temperature is

• diluted.

• saturated.

• supersaturated.

• unsaturated.

Sample A dissolves in water more slowly than sample B.

Sample B dissolves more slowly than sample C.

Which of the following best explains why sample A dissolves more slowly than the other two?

• It has the most volume.

• It has the smallest surface area.

• It has the largest number of sugar molecules.

• It has the fewest bonds between sugar modules.

What is Solubility? 

• What is dissolved 
• What does the dissolving
• A measure of how much solute can dissolve in solvent 
• a charged ion

• saturated
• unsaturated
• polar
• nonpolar

The "like dissolves like" rule is the reason why water cannot dissolve

• salt
• sugar
• vinegar
• oil
