Specific conductance/ Conductivity (k): - It is defined as the reciprocal of specific resistance, or resistivity, $\mathrm{k}=\frac{1}{\rho }$ $$\begin{array}{rl}& \mathrm{R}=\rho \frac{\ell }{\mathrm{A}}\\ & \frac{1}{\rho }=\frac{1}{\mathrm{R}}\cdot \frac{\ell }{\mathrm{A}}\\ & \mathrm{k}=\mathrm{G}\times {\mathrm{G}}^{\ast }\end{array}$$ 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 $\mathrm{k}$ is ohm ${}^{-1}{\mathrm{cm}}^{-1}$
