What are the primary components of a corrosion cell?

The primary components of a corrosion cell consist of an anode, a cathode, a metal path, and an electrolyte. Each of these elements plays a critical role in the electrochemical process that leads to corrosion.

The anode is the site where oxidation occurs; this is where metal loss happens as it gives up electrons. The cathode, on the other hand, is where reduction takes place, receiving electrons from the anode. The metal path connects these two electrodes, allowing for the flow of electrons, which is essential for the continuous operation of the corrosion cell. The electrolyte facilitates the movement of ions between the anode and cathode, completing the circuit necessary for corrosion to occur.

This arrangement forms the basis of the electrochemical reactions that underlie corrosion, making option B the accurate representation of the components involved in a corrosion cell. Understanding these elements is fundamental for anyone involved in cathodic protection and corrosion control methods.
