Résumé : CO2absorption in an initially quiescent aqueous solution of NaHCO3and Na2CO3 is studied in a Hele-Shaw cell, using a Mach-Zehnder interferometer. Chemo-hydrodynamical instabilities appear in the liquid phase below the interface after a certain time. A description of the observations and a preliminary simple modeling of this instability, based on the buoyancy-induced Rayleigh-Taylor mechanism, is presented.
