Construct a curve for the titration of 50.00 mL of 0.0500M HCl with 0.100 M NaOH. Use Excel to calculate the pH as a function of volume of titrant added and construct a pH curve. Hint: split the titration curve into three parts: the pre-equivalence point region after adding NaOH, the equivalence point, and points beyond the equivalence point. NOTE: A similar approach can be used to prepare the theoretical pH curves (pH calculated) for question 1 of Experiment 4. Simply replace Co(HCI), V(HCI) and C°(NaOH) with the correct values and adjust the V (NaOH) to the volumes measured/recorded during the experiment. For a weak acid and strong base titration the calculations will be slightly different (see Practical Guide p 33 -34).
