Label the areas of the curve where a buffer is present. Locate the point where pH= pKa (halfway to the equivalence point.) Label pKa on the graph. If the acid is polyprotic, label the pKa for each equivalence point on the graph. pKal = pK₁2 = Kal Calculate Ka for your unknown acid. f your unknown is polyprotic, calculate Ka at both the equivalence points. (Show work) (from the graph) K₁2 =
