Resumo: The simulation of the mass transfer behavior during the rise stage of a bubble containing a concentrated solute in the presence of an instantaneous chemical reaction on the liquid side can be easily obtained from first principles provided that depletion of solute does not affect the molecular and hydrodynamic behavior of the bubble. The effect of this common simplifying assumption is tested in dimensionless for versus the less constrained situation which allows for changes in the rise velocity and rate of transfer of solute along the bubble rising path. This assumption can be misleading and yield excessive values for the solute removal, and the degree of error increases with solute concentration, solute diffusivity, and bubble release pressure.
