The equivalent conductance ( ) of an aqueous solution of a strong electrolyte of concentration [X] is given by = ₀-A c^ 1 / 2 , where A is a constant and c is the concentration of the electrolyte. The specific conductance (with =1000 ~K / c ) of NaCl and KCl salt solutions (aqueous) are plotted against c . The correct figure is: (The plots are not drawn not to scale.)
