A heterogeneous chemical pattern formation, the so-called Liesegang phenomenon, was studied by means of computer simulation. A one dimensional algorithm based on Ostwald's supersaturation theory was developed and used for determining the effect of different initial conditions on the final structure. Four "reduced" parameters have been introduced that unambiguously determine the spacing coefficient of the final structure. The relationship between the initial concentration of the outer electrolyte and the spacing coefficient that was suggested by Matalon and Packter has been found to be valid only for high outer electrolyte concentrations.
