Redox products with inert electrodes?

Click For Summary
SUMMARY

The discussion centers on the oxidation-reduction reactions occurring at inert electrodes, specifically platinum and silver-coated electrodes, when a DC voltage is applied to a saline solution of KCl. The primary reactions identified are the generation of chlorine gas at the positive electrode and hydrogen gas at the negative electrode. Inert electrodes, such as platinum and silver, facilitate these reactions without undergoing any change themselves during the process.

PREREQUISITES
  • Understanding of oxidation-reduction (redox) reactions
  • Familiarity with electrochemistry concepts
  • Knowledge of inert electrodes and their properties
  • Basic principles of direct current (DC) voltage application
NEXT STEPS
  • Research the electrochemical properties of platinum and silver-coated electrodes
  • Study the detailed mechanisms of chlorine and hydrogen gas evolution reactions
  • Explore the effects of varying concentrations of KCl on redox reactions
  • Learn about the applications of inert electrodes in electrochemical cells
USEFUL FOR

Chemistry students, electrochemists, and professionals involved in electrochemical research or applications, particularly those focusing on redox reactions and inert electrode behavior.

TL;DR
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.
