Concept Introduction:
A chemical reaction is defined as a chemical change that occurs in the system when a substance combines with another one in order to form different species. The species initially present in the reaction are known as reactant species and the species that form after the completion of the chemical reaction are known as product species.

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.
