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

Text Solution

Verified by Experts

The correct Answer is:
`0.219 cm^(-1)`
`k=(1)/(2)xx(1)/(A)or(1)/(A)=kxxR=(0.146xx10^(-3)ohm^(-1)cm^(-1))xx(1500" ohm")`
`=219xx10^(-3)cm^(-1)=0.219cm^(-1)`
