The ___ is the thing being dissolved.

• solute

• solvent

• mixture

• solution

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

• dilution
• concentration
• saturated solution
• supersaturated mixture

What does it mean to dilute a solution?

• lower the concentration of solute per solvent
• increase the concentration of solute per solvent

What is a solute?

• The substance that does the dissolving in a solution.
• The substance that is dissolved into the solution.
• The mixing of different substances.
• The process in which neutral molecules lose or gain electrons

All substances have the same solubility.

• True

• False

If I dissolve carbon dioxide in water, what is my solvent?

• Carbon Dioxide
