Degree of Ionization |
(quantity of substance that is ionized)/(concentration of substance before ionization) |
|
|
Acid with two ionizable H atoms |
Diprotic acid |
|
|
Acid with three ionizable H atoms |
Triprotic acids |
|
|
Salt that is a conjugate base of a string acid is: |
Neutral |
|
|
Salt that is a conjugate acid of a strong base is: |
Neutral |
|
|
Salt that is a conjugate base of a weak acid is: |
Basic |
|
|
Salt that is a conjugate acid of a weak base is: |
Acidic |
|
|
How do you tell if a salt is acidic or basic is both parts come from a weak acid or base? |
Compare Ka and Kb values. The bigger one determines. |
|
|
Relationship between Ka and Kb |
Kw = Ka•Kb |
|
|
Shift in position of an equilibrium caused by addition of an ion involved in the reaction |
Common-ion Effect |
|
|
Henderson-Hasselbalch Equation |
pH = pKa + log[base]/[acid] |
|
|
Solution of a weak acid or base and it's conjugate partner (HA and A-). Resists changes in pH. |
Buffer solution |
|
|
Presence of carbonate in rivers, lakes protects natural waters from acid rain. Acid in acid rain neutralized by bicarbonate. |
Environmental buffer |
|
|
pH range within which a given buffer can provide pH protection. = pKa +- 1 |
Buffer Capacity |
|
|
Quantity of acid/base that a buffer can neutralize while maintaining pH within desired range. Function of concentration of components |
Buffer Capacity |
