In groups you will plot a titration curve (graph of pH as a volume of titrant added) for the reaction between a weak acid and a strong base. A) 40.00 ml of 0.10 M CH,COOH was titrated with 0.20 M NaOH. Calculate the pH after the addition of specific volumes of NaOH. (K, of CH,COOH = 1.8 x 10%) 0.00 ml of NaOH 10.00 ml of NaOH 20.00 ml of NaOH 0 25.00 ml of NaOH Show all your work for calculations. O o O B) Plot the titration curve using the calculated pHs in part A on large graph paper provided. O C) Label the following on the titration curve: o Initial PH Half equivalence point Equivalence point After equivalence point Final pH O O
