23. During a conductometric titration of a strong acid (like HCl) against a strong base (like NaOH), — Electrochemistry Chemistry Question

💡 Solution & Explanation

Highly mobile $H^+$ ions are initially replaced by less mobile $Na^+$ ions, causing a drop in conductance. At the equivalence point, conductance is at a minimum. Beyond this, the addition of highly mobile $OH^-$ ions causes conductance to rise rapidly (forming a V-shaped curve).
