$AgNO_{3}(aq)$ was added to an aqueous KCI solution gradually and the conductivity of the solution was measured. The plot of conductance (A) versus the volume of $AgNO_{3}$ is

Answer:

Option D

Explanation:

As $AgNO_{3}$ is added to the solution, KCI will be displayed according to the following reaction

 $AgNO_{3}(aq) +KCl(aq) \rightarrow   AgCl(s)+KNO_{3}(aq)$

For every mole of KCI displaced from the solution, one mole of KNO₃ comes into the solution resulting in almost constant conductivity. As the end point is reached, added AgNO₃ remain in solution increasing ionic concenkation, hence conductivity increases
