Solution
Verified by Toppr

When NaOH is added to acetic acid, there is a first gradual increase in the conductance and then there is a rapid increase in the conductance. This is because, first the more hydrated protons are replaced by sodium ions and then after complete neutralization of acetic acid, sodium ions and hydroxide ions are added to the solution.
