Basic Electrophoresis: Migration of Ions in an Electric Field—ChemTopic™ Lab Activity

firewatch

One of the most poorly understood concepts in electrochemistry has to do with the flow of electricity in an electrochemical cell. Many students assume that the flow is due to the flow of electrons. In electrochemical cells, electrons carry current through an external wire or conductor, but ions carry current through the solution. With the Basic Electrophoresis: Migration of Ions in an Electric Field—ChemTopic™ Lab Activity, explore the migration of ions in an electric field, a central feature of electrochemical cells and the basic principle in electrophoresis. Available as part of the Electrochemistry—ChemTopic™ Labs digital collection. Click the Price link for digital collection pricing.
