363.1. Consider corrosion of a galvanic coupler. Specify the anode and cathode of the corresponding galvanic couple.
2. Calculate the EMF.
3. Write the equations for the anodic and cathodic processes, the molecular equation for the corrosion reaction, indicate the direction of electron movement in the system.
4. Redox potentials of hydrogen, oxygen and metals in different media (Appendix 7).
