A student titrates a \(50.0\text{ mL}\) sample of \(0.10\text{ M }\text{CH}_3\text{COOH(aq)}\) with \(0.10\text{ M }\text{NaOH(aq)}\) at \(25\ ^\circ\text{C}\) and continuously monitors the electrical conductivity of the solution as a function of titrant volume. Up to the equivalence point (\(50.0\text{ mL}\) of titrant added), the electrical conductivity increases at a moderate, steady rate.

Which of the following best predicts and explains the behavior of the electrical conductivity as additional \(\text{NaOH(aq)}\) is added past the \(50.0\text{ mL}\) equivalence point?
