pH Titration Curves Olivia Downs 4/11/11 CHM1046L/85606 Alexis S., Alexis O., Christi The purpose of this experiment is to determine the pH of the acid-base potassium dihydrogen phosphate through the process of titration and graphical analysis. Volume and pH data for the raw data, first derivative, and second derivative titration plots are acquired. Theory The titration theory is when a basic or acidic solution of unknown concentration is reacted with an acidic or basic solution of known concentration. The acid and base combine and end up neutralizing each other. At the equivalence point, where the numbers of moles of base equal the number of moles of acid, the titration is finally complete. After titration is complete, a plot of the pH solution during titration is formed into a titration curve to show the calculated values. The indicator theory is often used in finding the endpoint of a titration. An indicator is a substance whose color depends on pH. The indicator monitors the pH of the acid-base reaction. The indicator in this experiment consists of a sensitive meter for measuring small voltages and a combination electrode/probe. When the indicator is placed in the solution, it forms an
