| Résumé : | CO2 absorption in an initially quiescent aqueous solution of NaHCO3 and Na2CO3 is studied in a Hele-Shaw cell. Using a Mach-Zehnder interferometer, refractive index variations in the liquid are followed during the absorption. It is observed that a boundary layer with different concentrations of the various chemical species is formed in the liquid, and grows continuously. However, after some time, this boundary layer eventually becomes unstable and a highly dynamical variation of the species concentration fields is observed in the liquid. |
