The resistance of a conductivity cell containing 0.001M KC1 solution at 298 K is 1500 . What is the cell constant if conductivity of 0.001M KC1 solution at 298 K is 0.146 x 10“3 S cm-1.

Explanation

Resistance `(R )=1500Omega`
Conductance `(C )=(1)/(R )=(1)/(1500 ohm) , =(1)/(1500)S`
Conductivity `(k)=0.146xx10^(-3)Scm^(-1)`
Cell constant `(l//a)=("Conductivity")/("Conductance")=(0.146xx10^(-3)Scm^(-1))/((1//1500S))=0.219cm^(-1)`
