The discussion centers on the role of diaphragms in charge transfer within electrochemical cells, specifically highlighting their function in preventing the mixing of solutions between half-cells while allowing ionic conductivity. It is established that the diaphragm facilitates charge transfer through a mechanism that involves selective ion exchange, where ions that do not react directly are allowed to pass. The concept of using a (double) ion exchanger is introduced as a critical component in designing these systems for optimal performance.
PREREQUISITESChemistry students, electrochemists, and researchers interested in the mechanisms of charge transfer and the design of electrochemical systems.
Borek said:Ions do travel through the membrane. However, you usually design the system in such a way that traveling ions are those that will not react directly.
