Diffusive fingering in a precipitation reaction driven by autocatalysis

Abstract

The interaction of an autocatalytic reaction with a fast precipitation reaction is shown to produce a permanent precipitate pattern where the major driving force is differential diffusion. The final structure emerges from the leading transient cellular front, the cusps of which evolve into precipitate free zones. The experimental observations are reproduced by a simple model calculation based on the empirical rate-law of the reaction.
