Activating the surface in electrochemistry?

Click For Summary
SUMMARY

The term "activate the surface" in electrochemistry refers to preparing the electrode surface to ensure optimal performance during experiments, particularly in corrosion resistance studies. This process often involves cleaning the surface to remove impurities that could hinder current flow and charge transfer. In the context of the discussion, using water during the grinding of the working electrode is a recommended practice to achieve this activation. The insights provided by Borek emphasize the importance of surface cleanliness in electrochemical applications.

Hi,

can someone please tell me what does an expression "to activate the surface" in electrochemistry mean?

Brief explanaiton of situation:
I am investigating the corrosion resistance of certain metals by means of electrochemical methods. During the grinding of the working electrode (tested metal), I was told to use water because that way "we activate the surface".

If someone could answer me this question I would appreciate it very much.


Thank you

Preparing the electrode surface so that it works as expected. Often it means just cleaning it so that the surface is not covered with any impurities that disturb the current flow/charge transfer.
 
Thanks, Borek, for you quick respond.

Regards
