|
pH of a buffered solution
|
Henderson-Hasselbalch equation
pH = pKa + log[conj. base]/[conj.acid] |
|
|
Neutralization
|
mixing of equal mole portions of an acid with a base regardless of their concentrations and strengths. (NOTE: does not mean to make the solution pH = 7)
|
|
|
Equivalence point for a weak acid and strong base
|
The point at which the weak acid is completely converted to its conjugate base. pH will be greater than 7 at the equivalence point.
|
|
|
Buffer
|
solutions that resist drastic changes in pH. Make of roughly equal mole mixture of a weak acid and its weak conjugate base.
|
|
|
Ka
|
[H+] x [conj. base]/[weak acid]
|
|
|
Acid
|
Proton donor, electron-pair acceptor, or a compound that yields H30+
|
|
|
Base
|
Proton acceptor, electron-pair donor, or a compound that yields OH- when added to water.
|
|
|
Arrhenius acid
|
yields H30+ when added to H20
|
|
|
Arrhenius base
|
yields OH- when added to H20
|
|
|
Bronsted-Lowry acid
|
Proton donor

Bronsted-Lowry base
|
Proton acceptor
i.e. KOH in protic solvent |
|
|
Lewis Acid
|
Electron pair acceptor
i.e. BF3 in aprotic solvent |
|
|
Lewis Base
|
Electron pair donor
i.e. NH3 in aprotic solvent |
|
|
Acid Dissociation, Ka
|
[H30+]*[A-]/[HA]
10^(-pKa) |
|
|
pKa
|
-logKa
|
|
|
Van der waals forces
|
Weak intermolecular attractive forces
|
|
|
Snell's Law
|
n1sin01 = n2sin02
n air approx. = 1 |
|
|
Faraday
|
1 mole of electric charge
