are thus the cathodic reactions of corrosion and the area of a corroding metal where these reactions occur is a cathode. POTENTIALS AND POLARISATION Since the corrosion reactions involve the transfer of electrons and ions between the metal and the solution the rates are equivalent to electric currents. The rates of these reactions depend on the potential difference between the metal and the...

Pourbaix diagrams help understand pH-dependent equilibria, which are often coupled to solubility equilibria and corrosion (which will be talked about more later). Latimer Diagrams Latimer diagrams are the oldest and most compact way to represent electrochemical equilibria for substances that have multiple oxidation states. how to make a wither skull banner It is common practice to superimpose these two lines (a) and (b) on Pourbaix diagrams to mark the water stability boundaries. Example problem 4.8 Some fuel cells operate by oxidizing hydrogen gas on an anode while reducing oxygen from ambient air in contact with a cathode.. How to read pool test strips

How To Read Pourbaix Diagrams

Pourbaix diagrams allow to determine the corrosion behavior of a metal in water solutions i.e. the direction of electro-chemical processes and the equilibrium state of the metal at a certain electrode potential in a water solution at a certain value of PH.

  • The problem is that the diagram isnt matching any of the diagrams at similar graphs in text books as well at same concentrations – the Cu system is one that is well studied and documented so there are lots of examples of what it should look like —the line should be vertical – its not in your app results…– to me it looks like there
