The resistance of a conductivity cell co...

The resistance of a conductivity cell containing 0.001 M KCl solution at 298 K is 1500 `Omega`. What is the cell constant if the conductivity of 0.001 M KCl solution at 298 K is `0.146 xx 10^(-3) S cm^(-1)` ?

Text Solution

Verified by Experts

Given, conductivity , `kappa = 0.146 xx 10^(-3) S cm^(-1)`
Resistance, R = 1500 `Omega`
`:. ` Cell constant `= kappa xxR`
`= 0.146 xx 10^(-3) xx 1500 = 0.219 cm^(-1)`
