Term
Solution
Definition
a homogeneous mixture of two or more substances
Term
Solute
Definition
substance that is dissolved in a solution
Term
Solvent
Definition
substance that does the dissolving in a solution
Term
Suspension
Definition
heterogeneous mixture consisting of small particles spread throughout a liquid or gaseous medium, from which they will eventually settle out
Term
Amalgam
Definition
solution with a liquid solute and a solid solvent
Term
Alloy
Definition
homogeneous mixtures of metals
Term
Dipole
Definition
molecule that has both negatively and positively charged poles caused by the unequal distribution of electrons
Term
Polar Molecule
Definition
molecule that has partially charged electrical poles
Term

process whereby a solvent breaks up an ionic solid
Term
Soluble
Definition
dissolvable
Term
Solubility
Definition
maximum amount of a solute that can dissolve in a given amount of solvent under normal conditions
Term
Miscibility
Definition
the property that allows two liquids to be soluble in each other
Term
Precipitate
Definition
solid formed during a reaction; insoluble in water
Term
Saturated
Definition
containing the maximum amount of a solute that can be dissolved in a given amount of solvent under normal conditions
Term
Super-saturated
Definition
having dissolved more than the normal amount of solute in a given amount of substance
Term
Insoluble
Definition
not able to be dissolved
Term
Henry's Law
Definition
the greater the pressure on a liquid, the greater the amount of gas that will remain dissolved in that liquid at any given temperature
Term
Percentage by Mass
Definition
a method of expressing the concentration of a solute as a percentage of the total mass of the solution
Term
Specific gravity
Definition
method of determining the concentration of a solution by comparing the density of the solution to the density of water
Term
Boiling Point Elevation
Definition
effect whereby a solute raises the boiling point of the solute in which it is dissolved
Term
Freezing Point Depression
Definition
effect whereby a solute lowers the freezing point of the solvent in which it is dissolved
Term

Definition
1. Solutions are homogenous, 2. Solutes cannot be filtered out, 3. Solutes do not settle out, 4. Components of a solutoin can be separated by physical means, 5. Liquid solutions are tranparent, 6. Solutions are of variable composition
Term
What is the Tyndall Effect?
Definition
It is when light passes through a liquid, the light will not be dispensed
Term
What happens to the solubility of a solution of gas and liquid when you increase the temperature?
Definition
the solubility decreases
Term
