WebSo, now that we're adding the conjugate base to make sure we have roughly equal amounts, our pH is no longer 2. It might be somewhere like a 5. So now we have a strong buffer with a lot of capacity, but our pH of this buffer solution is very different from the pH of just the weak acid/conjugate base we started with.

Polyprotic Acids Pathways to Chemistry

WebDepicted on the left is an idealized pH titration curve for a weak diprotic acid. The first thing that you should notice is that there are two regions where we see a significant pH change. These, if you wish, correspond to two separate titrations. Titration 1 is the reaction of the first proton with the base (in this case sodium hydroxide). Web(This is because the maximum pH that can be achieved with 0.100-M NaOH is 13.) The titration curve for the reaction of a polyprotic base with a strong acid is similar, but inverted on the pH scale. The initial pH is high; as acid is added, the pH decreases in steps if the successive p Kb values are well separated. Comments dust overlay for editing
