When a strong acid and a strong base are mixed, they react according to the following net-ionic equation: H₃O⁺(aq) + OH⁻(aq) → 2H₂O(l). If either the acid or the base is in excess, the pH of the resulting solution can be determined from the concentration of excess reactant. If the acid and base are equimolar, the pH of the solution is 7.00 at 25°C. View more lessons or practice this subject at www.khanacademy.org/science/a...
