Module 4—Properties of Solutions
Module Glossary
amount concentration: the proportion of solute (in moles) to volume of solution
aqueous phase: a phase denoting a highly soluble substance that has been dissolved in water; denoted by (aq)
Arrhenius acid: a substance that ionizes in water to produce hydrogen ions
Arrhenius base: an ionic compound that dissociates in water to produce hydroxide ions
concentration: a property of solutions; the mass, volume, or number of moles of solute present in proportion to the quantity of solvent or total solution
conductivity: the ability of a solution to transfer an electric current
dissociation: the separation of ions that occurs when an ionic compound dissolves in water
dynamic equilibrium: the idea that there is a balance between two opposing processes (forward and reverse) occurring at the same rate
electrolyte: a solution that conducts an electric current
endothermic: absorbing energy from the surroundings
exothermic: releasing energy to the surroundings
immiscible: a term used to describe liquids that do not dissolve in each other
ionization: a process by which a neutral atom or molecule is converted to an ion; the reaction of substances in water to create ions
nonelectrolyte: a solution that does not conduct an electric current
saturated solution: a solution that contains the maximum quantity of solute for a specified temperature; in which no more solute will dissolve at a specified temperature; at maximum solute concentration
solubility: the concentration of a saturated solution at a specified temperature
solute: a component of a solution, the material that dissolves in the solvent
solution: a homogeneous mixture of at least one solute dissolved in a solvent
solvent: a component of a solution, the material in which the solute dissolves
stock solution: a concentrated solution that is used in the preparation of more dilute solutions of the same solute
turbidity: the measure of the clarity of a clear liquid
