pH measurements: How to see the real face of electrochemistry and corrosion?

For several decades antimony electrodes have been used to measure the acidity/basicity -- and so to determine the pH value. Unfortunately, they allow for measuring pH changes of solutions only at a certain distance from electrodes or corroding metals. Researchers have now developed a method for producing antimony microelectrodes that allow for measuring pH changes just over the metal surface, at which chemical reactions take place.
