25.0 mL of 0.100 M HCl is titrated with 0.100 M NaOH. Calculate the pH of the resulting solution at each of the specified points in the titration. Initially: pH of HCl: After the addition of 15.0 mL of NaOH: a. Total volume: b. HCl in excess: c. concentration of remaining HCl: d. pH of solution: After the addition of 30.0 mL of NaOH: a. Total volume: b. NaOH in excess by: c. concentration of NaOH: d. pH of solution:
