Term
Solution
Definition
A mixture that has the same composition color, density, and taste throughout.
Term
Alloy
Definition
A solid solution
Term
Nonpolar molecules
Definition
Molecules with no separated positive and negative areas.
Term
Saturated Solution
Definition
A solution that contains all the solute it can hold at a given temperature.
Term
Unsaturated Solution
Definition
Any solution that can dissolve more solute at a given temperature.
Term
Supersaturated Solution
Definition
A solution that contains more solute than a saturated one at the same temperature.
Term

Definition
Charge particles
Term
Electrolytes
Definition
Solutions of ions that conduct electricity in water.
Term
Nonelectrolytes
Definition
Substances that form no ions in water and cannot conduct electricity.
Term
Dissociation
Definition
The process in which an ionic solid separates into positive and negative ions.
Term
Ionization
Definition
Molecules broken apart in such a way that the atoms take on a charge; the process of forming ions.
Term
What effect does solutes have on the physical properties of solvents?
Definition
They can change physical properties. They can lower the freezing point or raise the boiling point?
Term
Explain how you would make a 25 percent solution by volume of apple juice.
Definition
You would mix 25ml of apple juice with 75 ml of water.
Term
What three methods can increase the rate of dissolving a solid in a liquid?
Definition
Stirring, increase the temperature, and decrease the crystal size.
Term
Why will oil not dissolve in water?
Definition
Oil is nonpolar and water is polar. A polar molecule will not dissolve a nonpolar molecule.
Term
What type of solvent would you use to dissolve a polar solute?
Definition
A polar solvent like water.
