Diprotic Acids are compounds with two H+ ions
Diprotic Acids and Bases
Concept #1: Diprotic Acids possess 2 Ka values
Concept #2: Diprotic Acids can dissociate into 3 forms.
Example #1: Carbonic acid, H2CO3, represents a weak diprotic acid with Ka1 = 4.3 x 10-7 and Ka2 = 5.6 x 10-11. Determine the base dissociation constant associated with the carbonate ion, CO32–.
