Chemistry - Electrochemistry Question with Solution | TestHub

Initially, the solution contains highly mobile H⁺ ions, so conductance is high.

On adding the weak base, H⁺ ions are neutralized, causing conductance to decrease.

At the equivalence point, the concentration of H⁺ becomes minimum, so conductance is minimum.

After the equivalence point, excess weak base is only slightly ionized.

Therefore, conductance increases slowly beyond the endpoint.

Hence, the conductance vs. volume graph is Option (C).
