Term | Definition |
electrolyte | A substance that dissolves in water to give the solution the ability to conduct electricity |
pOH | hydroxide ion concentration |
titration | method used to determine the concentration of a substance in a solution |
Kb | Molal Boiling point constant |
Kf | Molal Freezing point constant |
neutralization | a chemical reaction in which an acid and a base react to form a salt |
molarity | Number of moles of solute in one liter of solution |
boiling-point elevation | The difference between the boiling points of the pure solvent and a nonelectrolyte solution of that solvent and is directly proportional to the molal concentration of the solution |
freezing-point depression | The difference between the freezing points of the pure solvent and a solution of a non electrolyte in that solvent, and is directly proportional to the molal concentration of the solution |
[H3O]+ | Hydronium |
[OH]- | Hydroxide |
end point | The point in a titration at which no more titrant should be added. It is determined, for example, by a color change in an indicator or by the appearance of a precipitate. |
base | proton acceptors identified by release of hydroxide ions |
acid | proton donors that yield hydronium ions in water solution |
molality | The concentration of a solution expressed in moles of solute per kilogram of solvent |
concentration | The amount of solute in a given amount of solvent in a solution. |
buffer | solutions that are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications |
solubility | The capability to dissolve |
dissociation | The separation of ions that occur when an ionic compound dissolves |
pH | hydrogen ion concentration |
colligative properties | Depend on the concentration of solute particles but not on their identity |
