The effect of dissociation of the invading electrolyte on the formation of Liesegang bands is investigated. We find, using organic compounds with known dissociation constants, that the spacing coefficient, 1 + p, that characterizes the position of the nth band as xn ∼ (1 + p)n decreases with increasing dissociation constant, Kd. Theoretical arguments are developed to explain these experimental findings and to calculate explicitly the Kd dependence of 1 + p.
