|
Boiling Point Elevation |
The difference between the boiling points of the pure solvent and a nonelectrolyte solution of that solvent, and it is directly proportional to the molal concentration of the solution. |
|
|
Colligative Properties |
Properties that depend on the concentration of solute particles but not on their identity. |
|
|
Dissociation |
Separation of ions that occurs when an ionic compound dissolves. |
|
|
Electrolyte |
A substance that yields ions and conducts an electric current in solution. |
|
|
Freezing Point Depression |
The difference between the freezing points of the pure solvent and a solution of a nonelectrolyte in that solvent, and it is directly proportional to the molal concentration of the solution. |
|
|
Ionization |
Ions are formed from solute molecules by the action of the solvent. |
|
|
Molal Boiling Point Constant |
The boiling-point elevation of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute. |
|
|
Molal Freezing Point Constant |
The freezing-point depression of the solvent in a 1-molal solution of a nonvolatile, nonelectrolyte solute. |
|
|
Net Ionic Equation |
Includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution. |
|
|
Nonelectrolyte |
A compound that dissolves but does not produce any ions in solution. |
|
|
Nonvolatile Substance |
A substance that has little tendency to become a gas under existing conditions. |
|
|
Spectator Ions |
Ions that do not take part in a chemical reaction and are found in solution both before and after the reaction. |
|
|
Strong Electrolyte |
Any compound whose dilute aqueous solutions conduct electricity well; this is due to the presence of all or almost all of the dissolved compound in the form of ions. |
|
|
Weak Electrolyte |
Any compound whose dilute aqueous solutions conduct electricity poorly; this is due to the presence of a small amount of the dissolved compound in the form of ions. |
