The resistance of a conductivity cell containing 0.001 M KCl solution at 298 K is 1500 Omega. What is the cell constant if conductivity of 0.001 M KCl solution at 298 K is 0.146xx10^(-3)S" "cm^(-1).

Answer»

SOLUTION :* Given,
CONDUCTIVITY, `k=0.146xx10^(-3)" S "cm^(-1)`
Resistance, `R=1500Omega`
`THEREFORE` Cell CONSTANT=`kxxR`
`=0.146xx10^(-3)xx1500`
`=0.219" S "cm^(-1)`
`=0.219cm^(-1). . . (becauseS=Omega^(-1))`
