Chapter 13 Flashcards
The separation of ions that occurs when an ionic compound dissolves.
Dissociation
Includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution.
Net Ionic Equation
Ions that do not take part in a chemical reaction and are found in solution both before and after the reaction
Spectator Ions
Ions are formed from solute molecules by the action of the solvent
Ionization
The H3O+ ion
Hydronium Ion
Any compound whose dilute aqueous solutions conduct electricity well
Strong Electrolyte
Any compound whose dilute aqueous solutions conduct electricity poortly
Weak Electrolyte
Properties that depend on the concentration of solute particles but not on their identity.
Colligative Properties
Has little tendency to become a gas under existing conditions.
Nonvolatile Substance
The freezing-point depression of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute.
Molal Freezing-Point Constant (K)
The difference between the freezing points of the pure solvent and a solution of a non-electrolyte in that solvent.
Freezing-Point Depression
The boiling-point elevation of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute.
Molal boiling-point constant
The difference between the boiling points of the pure solvent and a nonelectrolyte solution of that solvent.
Boiling-Point Elevation
Allows the passage of some particles while blocking the passage of others.
Semipermeable Membrane
The movement of solvent through a semipermeable membrane from the side of lower solute concentration to the side of highter solute concentration.
Osmosis
