PRESENTATION OUTLINE

SOLUTION

a homogeneous mixture of two or more substances in a single phase

AQUEOUS SOLUTION

any solution in which water is the solvent

SOLVENT

the dissolving medium in a solution

SOLUTE

the substance dissolved in a solution

SOLUBILITY

the amount of a substance required to form a saturated solution with a specific amount of solvent at a specific temperature

SUSPENSION

a mixture in which the particles in the solvent are so large that they settle out unless the mixture is stirred or agitated

COLLOIDS

mixtures formed by particles that are intermediate in size between those in solutions and suspensions

UNSATURATED

a solution that contains less solute than a saturated solution under the existing condition

SATURATED

a solution that contains the maximum amount of dissolved solute

SOLUBLE

capable of being dissolved

NON-SOLUBLE

incapable of being dissolved and becoming a solution

MISCIBLE

when liquids dissolve freely in one another in any proportion

IMMISCIBLE

when liquids are not soluble in each other

MOLARITY

the number of moles in one liter of solution

MOLALITY

the concentration of a solution expressed in moles of solute per kilogram of solvent

DISSOCIATION

the separating of a molecule into simpler molecules, atoms, radicals, or ions

IONIZATION

the process of adding or removing electrons from an atom or molecule, which gives the atom or molecule a net charge

ELECTROLYTE

a substance that dissolves in water to give a solution that conducts an electric current

STRONG ELECTROLYTE

a compound that completely or largely dissociates in an aqueous solution, such as soluble mineral salts

WEAK ELECTROLYTE

a compound that dissociates only to a small extent in aqueous solution

NON-ELECTROLYTE

a liquid or solid substance or mixture that does not allow an electric current

COLLIGATIVE PROPERTIES

a property that is determined by the number of particles present in a system but that is independent of the properties of the particles themselves

VAPOR PRESSURE LOWERING

BOILING POINT ELEVATION

the difference between the boiling point of a liquid in a pure state and in a solution

FREEZING POINT DEPRESSION

the difference between the freezing points of a pure solvent and a solution, which is directly proportional to the amount of solute present
