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
