View more lessons or practice this subject at If the acid is in excess, the pH can be determined from the concentration of excess H₃O⁺. If the base is in excess, the pH can be determined from the concentrations of B and HB⁺ after the reaction. If the acid and base are equimolar, the pH of the resulting solution can be determined by considering the equilibrium reaction of HB⁺ with water. When a weak base and a strong acid are mixed, they react according to the following net-ionic equation: B(aq) + H₃O⁺(aq) → HB⁺(aq) + H₂O(l). ![]()
