Question

Conductance measurements can be used to detect the end point of acid-base titrations. Which of the following plots correctly represent the end point of the titration of monobasic strong acid and a monoacidic strong base?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

For strong acid and base, dissociation is almost $100\%$. Here we have monobasic acid and monoacidic base. Now with addition of the base conductance of the solution decreases as it will initially neutralize the acids, but after the end point if we continue the addition of the base, now conductance will again increase since the number of basic ions will increase in the solution. So option (A) is correct here.
