Abstract

Evolution of Liesegang patterns in an electric field was studied experimentally in the AgNO3/K2Cr2O7/gelatine system. The distance of the last (nth) band as a function of their appearance time can be described by the equation Xn = c1t1/2 + c2t + c3. A numerical model, based on Ostwald's supersaturation theory, predicted the same functional law. Experiments showed that the ratio of the distances of two consecutive rings, the spacing coefficient, decreases with increasing electric field strength and this behaviour was also reproduced by the numerical model.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
