After completing this chapter, you will be able to:
Understand the role of the electric field in the transport of ions, and explain an important equation for electrochemical transport, the Nernst-Planck equation.
Understand how the electric field modifies the transport rate and the apparent diffusivity of ions.
Explain how the field in turn is dependent on the diffusion rate.
Understand the concept of charge neutrality and how this concept can be used to simplify the models to calculate the electric potential.
Apply the modeling concepts to three prototypical problems in electrochemical transport: transport across an uncharged membrane, transport across a membrane carrying ...
