In summary, in basic chemistry courses, it is taught that a diaphragm prevents the mixing of solutions between half-cells while allowing for ionic conductivity. Despite neither electrons nor ions from the solution carrying charge through the diaphragm, ions are still able to travel through it. Typically, the system is designed so that only non-reactive ions are able to pass through the membrane, possibly through a double ion exchanger mechanism.

In basic chemistry courses you will learn that diaphragm prevents mixing of solutions between half-cells while maintaining ionic conductivity. What exactly carries charge through diaphragm if it's neither electrons, nor ions from the solution? What is the molecular mechanism behind that?

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.

So it's some kind of (double) ion exchanger?
 

FAQ: Exploring the Charge-Carrying Capability of Diaphragms in Chemistry

What is the purpose of exploring the charge-carrying capability of diaphragms in chemistry?

The purpose of this research is to understand the role of diaphragms in chemical reactions as they can act as barriers for charged particles to pass through. This can provide insights into improving the efficiency of chemical reactions and developing new technologies.

How do diaphragms affect the movement of charged particles in chemical reactions?

Diaphragms can either facilitate or hinder the movement of charged particles in chemical reactions depending on their properties such as thickness, material composition, and surface charge. They can also influence the direction and speed of the charged particles.
