pH
|
Used to express the acidity or alkalinity of a solution on a scale of 0 to 14, where less than 7 represents acidity, 7 neutrality, and more than 7 alkalinity
pH = -log[H+] pOH = -log[OH-] |
|
|
Polyprotic acid
|
Acids that donate more than one proton
|
|
|
Salts
|
Ionic compounds that dissociate in water
|
|
|
Titrate
|
Drop-by-drop mixing of an acid and a base to find the concentration of some unknown by comparing it with the concentration of the titrant
|
|
|
Half equivalence point
|
Exactly one half of the acid has been neutralized by the base
|
|
|
Henderson-Hasselbalch equation
|
(Half equivalence point)
pH = pKa + log [A-]/[HA] |
