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

Options

A. `(P)`
B. `(Q)`
C. `(R)`
D. `(S)`

Answer

D

Explanation

`As AgNO_(3)` is added
`K^(+) +CI^(-) +Ag^(+) +NO_(3)^(-) rarr AgCI(s) darr +K^(+) +NO_(3)^(-)`
Number of ions are approximately constant, when `AgNO_(3)` is added till equivalence point. After equivalence point number of ions, increases and hence conductivity.
