PRESENTATION OUTLINE
Solution:
A homogeneous moisture of two or more substances in a single phase
Solvent:
Dissolving medium In a solution
Solute:
Substance dissolved I'm a solution
Solubility:
The ability of one substance to dissolve in another at a given temperature and pressure. the amount of solute it takes Ina set amount of solvent to make a saturated solution
Suspensions:
A mixture when the particles in a solvent are so large that they settle out unless the mixture is constantly stirred or agitated
Colloids:
(colloidal dispersions) Particles that are intermediate in size between those in solutions and suspensions form mixture know
Unsaturated:
A solution that contains less solute than a saturated solution under the existing conditions
Saturated:
A solution that contains the maximum amount of dissolved solute
Soluble:
Capable of being dissolved
Non-soluble:
Incapable of being dissolved
Miscible:
Liquids that dissolve freely in one another in any proportion
Immiscible:
Liquids that are not soluble in each other
Molarity:
The number of moles of solute in one liter of solution
Molality:
The concentration of a solution expressed in moles of solute per kilogram of solvent
Dissociation:
The separation of ions that occurs when an ionic compound dissolves
Ionization:
The process of adding or removing electrons from an atom or molecule, giving it 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
Weak electrolyte:
A compound that dissociates only to a small extent in an 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
Boiling point elevation:
The difference between the boiling points of a pure solvent and a solution of non-electrolyte in that solution. Directly proportional to the solution's molar concentration
Freezing point depression:
The difference between the freezing points of a pure solvent and a solution of non-electrolyte in that solution. Directly proportional to the solution's molar concentration
