impedance between two electrode

I would like to calculate the magnitude of the impedance between a pair of the same electrode over a frequency range of 1 to 100,000Hz. But I am very confusing about it.

Experimentally,the electrodes are put into a beaker of physiological saline solution and a low-level sinusoidal excitation so that the impedances are not affected by current crossing the electrodes interface.
Assume the impedance of the saline solution is small enough to be neglected.
