Potentiometric Titration - Data Report Results Standardized NaOH solution concentration: 0.1198 M Volume of Unknown Acetic Acid solution pipetted in beaker (mL): 2.00 ml 1. Complete the data table below (add additional rows as required). Indicate the volume of titrant added at the equivalence point using bold text (see the illustrative example (Table 2) in the lab protocol to help you with your table). [2 marks] Table 1: Volume (mL) of standardized NaOH titrant added to acetic acid analyte solution examined through potentiometric titration (pH). Calculation of the slope of the curve ((( pH/ Volume of titrant) is also included.
