Effect on Conductance in Titration

Q.

Assertion: when NaOH is added to the HCl solution, the conductance of the solution decreases right upto the equivalence point and then increases.
Reason: At starting, fast moving to ions replaced by relatively slower moving $N{a}^{\oplus }$ ions and after the equivalence point, as $O{H}^{-}$ start increases conductance increases.
