Scenario: Titration of 40.0 mL 0.140 M HCI with 0.224 M NaOH Note: As you perform the following calculations you can complete the table on page 7, and then build the titration curve. The tabulated results will make it easy for you when you go to the computer lab and use Excel to graph the titration curves in the last stage of this exercise a) Calculate the milli-equivalents of H' in the titrand solution, before any NaOH has been added b) What volume of NaOH would need to be added to reach the equivalence point? What is the pH of the solution at the start of the titration, before any NaOH has been added? c) d) What is the pH of the solution after 4 ml of NaOH have been added? e) What is the pH of the solution after 14 mL of NaOH have been added? f) What is the pH of the solution after 21 mL of NaOH have been added?
