The interplay between hydrodynamics and chemistry can give rise to complex non linear dynamics. To study how a simple A+B→C reaction can affect buoyancy-driven instabilities, we experimentally investigate convective flows appearing at the miscible interface between a solution of a reactant A put on top of a solution of another reactant B in the gravity field when a reaction takes place. The main observation is that the symmetry of the hydrodynamic patterns is drastically modified by the chemistry.
