Calculating the pH at equivalence of a titration
A chemist titrates 210.0 mL of a 0.1003 M hydrobromic acid (HBr) solution with 0.7550M KOH solution at 25 °C. Calculate the pH at equivalence.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
