We've neutralized half of the acids, right, and half of the acid remains. And using Henderson Hasselbalch to approximate the pH, we can see that the pH is equal to the pKa at this point. So let's go back up here to our titration curve and find that. Alright, so the pH is 4.74. readiness nco ncoer example
