WebbCalculating pH for Titration Solutions: Strong Acid/Strong Base A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH (the titration curve is shown in Figure 14.18). Calculate the pH at these volumes of added base solution: (a) 0.00 mL (b) 12.50 mL (c) 25.00 mL (d) 37.50 mL. Solution WebbThe following table really is the full analytical solution to a titration of a weak base (B) with a strong acid (HCl). The data (volume of titrant and pH) can be copied and pasted into a program (Excel) to plot the curve. This algorithm actually uses pH as the input and finds the right volume that produces that pH.
