`AgNO_(3)(aq.)` was added to an aqeous `KCl` solution gradually and the conductivity of the solution was measured. The plot of conductance `(Lambda)` versus the volume of `AgNO_(3)` is :

Options

A. P
B. Q
C. R
D. S

Answer

D

Explanation

As `AgNO_(3)`, is added to solution, KCl will be displaced according to following reaction
`AgNO_(3)(aq)+KCl (aq)toAgCl(s)+KNO_(3)(aq)`
for every mole of KCl displaced from solution, one mole of `KNO_(3)` comes in solution resulting in almost constant conductivity. as the end point is reached, added `AgNO_(3)` remain in solution increasing ionic concentration. hence conductivity increases.
