And let's look at what each represents. Let's look at the first one. What the first one represents is it's the point at which all of this guy has been neutralized to this guy. So there's no more of this guy, and 100% of our solution is in this form at this point. Now, what the second point means is it's the point at which all of this guy has been neutralized into our final conjugate base. And at this point, as a second equivalence point, all of our solution is in this form.
