Diprotic acid dissociation reactions H 2 A H + + HA - , first proton dissociation constant, KA1 HA - H + + A 2-
Diprotic acid dissociation reactions
H2A H+ + HA-, first proton dissociation constant, KA1
HA-H+ + A2-, second proton dissociation constant, KA2
CT = [H2A] + [HA-] + [A2-]
Derive and express ionization factions (0, 1 and 2) as function of hydrogen ion concentration ([H+]).
Here, 0 = [H2A]/CT, 1 = [HA-]/CT, and 2 = [A2-]/CT
