For the titration of 25.00 mL of 0.100 M NaOH with 0.100 M HCl, calculate the pOH at a few representative points in the titration, sketch the titration curve of pOH versus volume of titrant, and show that it has exactly the same form as Figure 17-8. Then, using this curve and the simplest method possible, sketch the titration curve of pH versus volume of titrant.
