And in fact, this reaction is 10,000 times more likely than this reaction. So, in the same way that we spoke about titration curves of monopolic acids, we can also talk about titration curves of polyphonic acids. So here's our titration curve. While the Y axis is PH and the X axis is volume based at it. Now, this curve is for our hypothetical phypotic acid, h two A. Now, this guy will have not one equivalence point, but two equivalence points.
