Abstract:
Co(OH)2 Liesegang periodic precipitation systems exhibit oscillations in the number of bands due to band redissolution in high NH4OH concentration. We revisit the problem previously considered (Nasreddine and Sultan, J. Phys. Chem. A 1999, 103, 2934-2940) by rigorously refining the experiments and the Chaos analysis. Chaos is established in this diffusion-precipitation-redissolution system, as is evident from the refined outputs of the Chaos analysis tools. A brief account of possible applications of Chaos in Liesegang systems is presented.
