Date Submitted: 4/03/06 Instructor: Daniel Schoonover pH Titration Objective The objective of this lab is to perform a pH titration of a mixture of a strong and weak acid and to graph the results. One should use the graph to calculate the concentrations of the strong and weak acid in the mixture. Experimental Data Concentration NaOH 0.25 M Initial volume of unknown 25.0 mL 20 drops from burette is about 1.00 mL mL of added base (NaOH) pH 0.00 1.96 0.80 2.00 2.00 2.03 3.05 2.06 4.10 2.10 5.02 2.14 6.05 2.19 7.00 2.26 8.09 2.39 9.00 2.56 9.50 2.72 9.79 2.83 10.02 3.09 10.60 3.29 10.89 3.44 10.92 3.47 11.31 3.65 11.48 3.69 11.69 3.76 11.90 3.83 12.13 3.89 12.30 3.94 12.55 4.00 13.53 4.21 14.60 4.41 15.51 4.57 16.70 4.78 17.52 4.95 18.50 5.21 18.70 5.26 18.98 5.35 19.05 5.38 19.11 5.40 19.25 5.47 19.65 5.66 19.78 5.76 19.91 5.92 20.09 6.17 20.28 6.68 20.41 9.73 20.50 10.17 20.57 10.30 20.65 10.46 20.70 10.53 20.85 10.71 21.00 10.83 21.60 11.09 21.75 11.15 22.05 11.24
