Solubility, Acids, and Bases

Describe a solute.

• part of solution present in largest amount
• gets dissolved
• water
• surrounds and breaks apart

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 super amount of solvent in it. 

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

• Saturated
• Unsaturated
• Supersaturated
• Homogeneous solution
