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.
