Using specifically developed experimental coloring methods allowing high spatial and temporal resolutions , we explore the mass transfer of oxygen around a bubble rising in various reactive media and the oxygen transport in their wake. Scaling laws for Sherwood numbers have been identified for a large range of Peclet number where various types of bubble motion develop.
