PRESENTATION OUTLINE

Solution:
Homogeneous mixtures of two or more substances in a single phase

Aqueous Solution:
A solution where the solvent is a liquid

Solvent:
Dissolving medium

Solute:
Substance dissolved in a solution

Solubility:
Amount of substance to make a solution saturated

Suspension:
A heterogeneous mixture where solute-like particles settle out of a solvent-like phase

Colloid:
A heterogeneous mixture in which solute particles do not settle out

Unsaturated: solution that can dissolve more particles
Saturated: solution that is unable to dissolve more particles

Soluble: able to dissolve
Unsoluble: unable to dissolve

Miscible: (liquids) forming a homogeneous solution when added together
Immiscible: (liquids) not forming a homogeneous mixture when added together

Molarity: number of moles of solute/liter of solution
Molality: concentration expressed as number of moles of solute/ kg solvent

Dissociation: in a an aqueous solution, the process in which a solid ionic compound seperates into its ions

Photo by brianc

Ionization: the breaking up of a compound into seperate ions
Electrolyte: a substance whos aqueous solutions conduct electricity

Strong Electrolyte: conducts electricity well
Weak Electrolyte: conducts electricity poorly
Non-electrolyte: does not conduct electricity

Colligative Propeties: physical properties of solutions that only depend on the number of particles

Vapor Pressure Lowering: the vapor pressure of a solvent in a solution is always lower than the vapor pressure of the pure solvent

Boiling Point Elevation: boiling points of solutions are higher than the boiling points the pure solvent

Freezing Point Depression: freezing points of solutions are lower than that of the pure solvent
