Electrodeposition of Lead from Lead Acetate and its fractal character

Electrodeposition of lead in the form of dendritic patterns is studied using circular cell geometry and the electrolyte used is lead acetate solution.The electrodeposits so obtained have crystalline appearance and the deposits are in the form of wide leaves with secondary and tertiary branches at the characteristic angles in accordance with the crystal structure. The growth of electrodeposits and the shape and branching pattern gets modified as the size of the deposit increase and branches tend to approach outer anode. Characterization of selected dendritic patterns in terms of fractal dimensions is presented.  It is shown that electrodeposits of lead obtained from lead acetate solution possess self similarity and scale invariance and have fractal character. Comparison of electrodeposits at two different cell operating voltages and two different electrolyte concentrations is discussed using the concept of fractals and fractal dimension.
