diffusion layer (concentration boundary layer)

https://doi.org/10.1351/goldbook.D01725
The region in the vicinity of an electrode where the concentrations are different from their value in the bulk solution. The definition of the thickness of the @D01716@ layer is arbitrary because the concentration approaches asymptotically the value \(c_{0}\) in the bulk solution (see diagram).
