|
acid
|
produces H+
|
|
base
|
produces OH-
|
|
Bronsted-Lowry Acid and Base
|
Acid = donates protons
Base = accepts protons |
|
Lewis Acid and Base
|
acid = electron-pair acceptor
base = electron-pair donor |
|
pH
|
ph =
-log[H+] = log(1/[H+]) |
|
pOH
|
pOH =
-log[OH-] = log(1/[OH-]) |
|
Water Dissociation Constant (Kw)
|
Kw =
[H+][OH-] = 10^(-14) gives pH + pOH = 14 |
|
Percent Ionization
|
PI =
(ionized acid concentration at equilibrium) / (initial concentration of acid) x 100% |
|
Acid Dissociation Constant (Ka)
|
Ka =
[H3O+][A-] / [HA] |
|
Base Dissociation Constant
(Kb) |
Kb =
[B+][OH-] / [BOH] |
|
Henderson-Hasselbalch Equation
|
pH = pKa + log([conjugate base] / [weak acid])
pOH = pKb + log([conjugate acid] / [weak base]) |
