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. 

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

• Saturated

• Unsaturated

• Mixture

• Homogeneous solution

__________ are made up of solutes and solvents.

• Solutions
