Question

The resistance of a conductivity cell containing $0.001MKCl$ solution at $298K$ is $1500\Omega$. What is the cell constant if conductivity of $0.001MKCl$ solution at $298K$ is $0.146\times {10}^{-3}Sc{m}^{-1}$.

Answer 1

Conductivity of the cell, k $=0.146\times {10}^{-}3Sc{m}^{-1}$

Resistance of the cell, R $=1500\Omega$

$\text{Cell constant}=k\times R$

$=0.146\times {10}^{-3}\times 1500$

$=0.129c{m}^{-1}$
