What is the purpose of the return path in a corrosion process?
What is the purpose of the return path in a corrosion process?
- To increase the rate of corrosion
- To allow electrons to move from the anode to the cathode (correct)
- To prevent the corrosion reaction from taking place
- To create a barrier between the anode and cathode
Why is a metallic pathway necessary for the corrosion reaction to occur?
Why is a metallic pathway necessary for the corrosion reaction to occur?
- It acts as a physical barrier preventing the corrosion reaction
- It provides a medium for the transfer of electrons between anode and cathode (correct)
- It increases the resistance to electron flow
- It has no impact on the corrosion process
What would happen if there were no metallic pathway joining the anodic and cathodic areas during corrosion?
What would happen if there were no metallic pathway joining the anodic and cathodic areas during corrosion?
- The corrosion would be less severe
- The corrosion rate would increase
- The corrosion reaction could not take place (correct)
- The anode and cathode would switch roles
