Chapter 16. Mass Transport in Electrolytic Systems

Learning Objectives

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 ...
