Chemistry · L4 · Polyprotic acids: stepwise dissociation, successive Ka values, and multi-equivalence-point titrations
Stepwise dissociation of di- and triprotic acids, why successive Ka values fall (Ka1 > Ka2 > Ka3), a full worked pH calculation across both steps of a diprotic acid, the shape of a polyprotic titration curve, and which species dominates at a given pH.
