I have to draw a pH curve for an acid with Ka1= 1.42x10^-3 (pKa1=2.847) and Ka2=2.01x10^-6 (pKa2=5.696).
There is a 25mL sample of 0.100M of this acid, H2A that is being titrated with 0.100M NaOH.
The initial pH of the acid is 1.924. How do I find the pH at both equivalence points?
I don't want Oxford to know I only got an A...
