The equivalent conductance ($\mathrm{\Lambda }$) of an aqueous solution of a strong electrolyte of concentration $\left[\mathrm{X}\right]$ is given by $\mathrm{\Lambda }={\mathrm{\Lambda }}_0-{\mathrm{Ac}}^{1/2}$, where $\mathrm{A}$ is a constant and $\mathrm{c}$ is the concentration of the electrolyte. The specific conductance $\mathrm{\kappa }$ (with $\mathrm{\Lambda }=1000\mathrm{\kappa }/\mathrm{c}$ ) of $\mathrm{NaCl}$ and $\mathrm{KCl}$ salt solutions (aqueous) are plotted against $\mathrm{c}$. The correct figure is: (The plots are not drawn to scale.)
