Solution
Specific conductance/Conductivity (к):-
It is defined as the reciprocal of specific resistance, $\kappa=\frac{1}{\rho}$
$\begin{aligned}
\mathrm{R} & =\rho \frac{\ell}{\mathrm{A}} \\
\frac{1}{\rho} & =\frac{1}{\mathrm{R}} \cdot \frac{\ell}{\mathrm{A}} \\
\mathrm{K} & =\mathrm{G} \times \mathrm{G}^{\circ}
\end{aligned}$
Specific conductance $=$ Conductance $\times$ cell constant Hence specific conductivity of a solution is defined as the conductance offered by $1 \mathrm{~cm}^3$ of electrolytic solution. Unit of $\mathrm{\kappa}$ is ohm ${ }^{-1} \mathrm{~cm}^{-1}$
