Module content and teaching

Principal aims

Electrochemistry plays an important role not only in physical chemistry, but in many areas of science in general: from biology (e.g. nerve signalling, vision) through chemistry (e.g. synthesis and analysis) to materials science (e.g. design of novel materials, such as nanowires and nanoparticles) and physics (e.g. electronics). Students will be provided with an introduction to the fundamentals of electrochemistry and solution properties and the role of electrochemistry in many of the areas highlighted above.

Principal learning outcomes

By the end of the module the student should be able to: Understand how simple ions added to aqueous solution affect the structure of water; Appreciate the concept of ideal and non-ideal solutions and the difference between activity and concentration; Know the Debye-Huckel equation and understand how and when to apply; Understand why a solution conducts electricity and how it can be measured; Appreciate the difference between conductivity and molar conductivity and how these values vary between strong and weak electrolytes; Understand which factors control the mobility of an ion in solution (Stokes Law) and why certain ions have anomalous mobilities; Understand the principles of scanning tunnelling microscopy (STM); Appreciate what is meant by the electrical double layer (EDL) and how the EDL effects colloid stability; Understand how to measure a galvanic potential using a two electrode arrangement and how to write the cell equation; Understand the relationship between the cell potential; Appreciate how to measure a standard electrode potential using a standard reference electrode; Know the Nernst equation and thus appreciate how varying the concentration of ions in solution alters the cell potential. Application to batteries, fuel cells and pH electrode; Understand how drugs can be administered to the body using the principles of diffusion (transdermal) and migration (iontophoresis); Understand Randles Sevcik equation and the shape of voltammetric curves at macro-sized electrodes. Application in electroanalysis; Understand experimental arrangement for dynamic electrochemical experiments; Appreciate mass transport in a dynamic electrochemical system and in the interplay between electron control and mass transport controlled: Focus on diffusion-controlled processes; Appreciate how membrane potentials arise in cells and how electrical signals are transmitted in nerve cells. Knowledge of the Goldman-Hodgkin-Katz equation is necessary ;Understand experimental arrangement for dynamic electrochemical experiments; Appreciate mass transport in a dynamic electrochemical system and in the interplay between electron control and mass transport controlled: Focus on diffusion-controlled processes; Understand Randles Sevcik equation and the shape of voltammetric curves at macro-sized electrodes. Application in electroanalysis
