It is shown that the often used representations of the ionic atmosphere surrounding a charged spherical particle suspended in an electrolyte solution and moving with electrophoretic velocity under the action of an applied electric field are misleading at best. Numerical results for the actual out of equilibrium counterion, co-ion, total ion, and total charge density distributions are presented.
Figure Legend: Density of counterions around a charged colloidal particle in a DC electric field. The electrophoretic velocity points towards the left.
