Redox products with inert electrodes?

In summary, redox products with inert electrodes involve the transfer of electrons between a reducing agent and an oxidizing agent using electrodes that do not participate in the reaction. This is different from active electrodes, which undergo changes in their oxidation state. Examples of inert electrodes include platinum, gold, and graphite, and they are advantageous for their stability, versatility, and interference-free nature. These types of reactions are commonly used in research to study kinetics and in industry for the production of chemicals, metals, and energy.

TL;DR Summary
What are the oxidation-reduction reactions that are produced at the electrodes when they are considered inert (platinum or silver coated)?
Hello,
What are the oxidation-reduction reactions that are produced at the electrodes when they are considered inert (platinum or silver coated)?
Let's take a simple example of a saline solution of KCl and apply a DC voltage between the two electrodes.
Thank you in advance.

OK,
It seems elementary: Chlorine on one side (positive electrode) and hydrogen on the negative electrode.

Yes. Inert electrode just transfers charge and doesn't change itself in the process.

Thanks for the confirmation, Borek.
 

1. What is a redox reaction?

A redox reaction is a chemical reaction in which there is a transfer of electrons between two substances. One substance loses electrons (oxidation) and the other gains electrons (reduction).

2. What are inert electrodes?

Inert electrodes are electrodes that do not participate in the redox reaction. They do not react with the substances in the reaction and remain unchanged throughout the reaction.

3. How do inert electrodes affect the redox reaction?

Inert electrodes do not affect the redox reaction itself, but they provide a surface for the transfer of electrons to occur. This allows for the flow of electricity in the reaction.

4. What are some examples of inert electrodes?

Some examples of inert electrodes include platinum, gold, and graphite. These materials do not react with most substances and are commonly used in redox reactions.

5. What is the purpose of using inert electrodes in redox reactions?

Inert electrodes allow for the separation of the redox reaction from the electrode material. This prevents contamination of the reaction and allows for accurate measurement of the reaction's progress.
