What is Diphenylacetic Acid Titration Analysis about?
This document describes an experiment using potentiometric titration to identify and determine the concentration of an unknown weak acid. Figures 1-4 show the titration curve, first derivative plot, second derivative plot, and linear plot used in the analysis. The equivalence point was determined to be 8.3 mL of NaOH with a pH of 6.42. The pH at the half equivalence point was calculated to be 3.94 using the linear plot. This identified the unknown acid as diphenylacetic acid with a pKa of 3.94 and concentra
