Calculate the pH of the resulting solution. 19. Titration of a strong acid with a strong base. A. For those of you who love all things science , living organisms (especially anatomy) and how stuff works in the human body then this is the quiz for you. Multiple Choice The end point for a titration can be determined graphically.The end point volume for a second derivative plot corresponds to:____________________. Simple pH curves.
