Question

The resistance of a decinormal solution of an electrolyte in a conductivity cell was found to be $245$ ohms Calculate the equivalent conductivity of the solutions.

Answer 1

$G=\frac{1}{a}=\frac{2}{3.5}=0.571cm$

$resistivity=\frac{R}{G}=\frac{245\Omega }{0.571cm}=429.07\Omega$

$conductivity\frac{1}{p}\frac{1}{429.07}=0.00235cm$

$\frac{1000\times k}{c}=\frac{1000\times 0.0023}{0.1}=23.03scm$
