Choose the correct representation of conductometric titration of benzoic acid vs sodium hydroxide.

In a conductometric titration of benzoic acid (weak acid) with NaOH (strong base):

Before the equivalence point: The weak acid is gradually neutralized. Benzoic acid is a weak electrolyte, so its solution has low conductance. As NaOH is added, the poorly conducting benzoic acid is replaced by highly conducting sodium benzoate. However, the OH⁻ ions (high conductivity) are consumed. Overall, conductance initially decreases slightly then increases as more sodium ions and benzoate ions are formed.

At equivalence point: All acid is neutralized.

After equivalence point: Excess NaOH adds highly mobile OH⁻ ions, sharply increasing conductance.

The graph shows a V-shape (decreasing then increasing after equivalence).

The correct answer is Option 1.
