The instability and breakup of laminar liquid jets in gaseous surroundings is investigated for conditions under which a solute is transferring across the jet interface rendering the system susceptible to Marangoni convection. Linear hydrodynamic stability analysis reveals that solute transfer out of the jet is stabilizing (produces longer jets) while transfer into the jet is destabilizing and promotes breakup. Solute adsorption, including as a limiting case the presence of a spread surfactant monolayer, may strongly counteract the stabilizing or destabilizing effects of mass transfer but has only a negligible effect on jet stability in the absence of interphase mass transfer. Qualitative experimental results for water jets in air with acetone as the transferring solute corroborate both the stabilizing and destabilizing mass transfer effects predicted by the theory.
