Term
Autoionization
Definition
The spontaneous dissociation of water
Term
Arrhenius Definition of Acids and Bases
Definition
Acids produce H+ in aqueous solution, and bases produce OH- in aqueous solutions
Term
Lewis Definition of Acids and Bases
Definition
Acids are electron acceptors in solution. Bases are electron donors in solution
Term
Bronsted-Lowry Definition of Acids and Bases
Definition
Acids are proton donors; bases are proton acceptors.
Term
Hydrodium Ion
Definition
H30+, which is H20 with the H+ proton
Term
Amphoteric
Definition
Molecules and ions that can be either acids or bases
Term
Strong Bases
Definition
Group 1 hydroxides and barium combined with OH-
Term
Kw
Definition
10 to the -14 power M.
Term
pH
Definition
-log[H+]
Term
Conjugate Pairs
Definition
a pair of molecules that have identical molecular formulas except that one has an additional H+
Term
Ionic Equilibrium
Definition
The equilibrium between a weak acid and it's conjugate base
Term
Buffer
Definition
Solutions used to minimize a change in pH that consist of a conjugate pair of a weak acid and weak base.
Term
Tirant
Definition
The unknown strong acid or base added to an unidentified base used to figure out the pH or that unknown base or acid.
Term
Tiration Curve
Definition
A curve obtained by plotting pH as a function of the volume of added tirant
Term
Equivalence point
Definition
The highest point on the tiration curve. This tells at what level the subject acid or base has been neutralized
