In an aqueous solution, how does specific conductivity of electrolytes change with the addition of water?


The conductivity of a solution by definition at any given concentration is the conductance of one unit volume of solution kept between two platinum electrodes with a unit area of cross-section and at a distance of unit length.

G=


Where


G is the conductance


κ is the conductivity


A is the area of cross-section


l is the distance between the platinum electrodes


Now, the addition of water dilutes the electrolyte. The number of ions in a given volume decreases and conductivity also reduces.
