Unit 6 Flashcards
pH
Hydrogen ion concentration
Titration
Method used to determine the concentration of a substance in a solution.
Dissociation
The separation of ions that occur when an ionic compound dissolves.
Electrolyte
A substance that dissolves in water to give the solution the ability to conduct electricity.proton acceptors identified by release of hydroxide ions.
Base
Proton acceptors identified by release of hydroxide ions.
H3O+
Hydronium
Molarity
Number of moles of solute in one liter of solution
Molality
The concentration of a solution expressed in moles of solute per kilogram of solvent
Colligative Properties
Depend on the concentration of solute particles but not on their identity.
Acid
Proton donors that yield hydronium ions in water solution
Concentration
The amount of solute in a given amount of solvent in a 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.
Kf
Molal Freezing point constant
Kb
Molal Boiling point constant
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.
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.
Neutralization
A chemical reaction in which an acid and a base react to form a salt.
pOH
Hydroxide ion concentration
OH-
Hydroxide ion
