In a corrosion cell, what charge does the anode have?

Neutral
Negative
Positive
Variable

The correct answer is: Positive

In a corrosion cell, the anode has a negative charge. This is because during the electrochemical process, oxidation occurs at the anode, where metal ions are released into the solution. As metal loses electrons, it becomes positively charged, which leads to a flow of electrons from the anode to the cathode. The anode's negative charge is a key concept in understanding how corrosion processes work, as it drives the electrical current through the electrochemical cell. The electrons released from the anode are consumed at the cathode, where reduction occurs, typically involving the gain of electrons by another substance, such as oxygen in the case of many corrosion processes. The understanding of the charge of the anode is crucial for anyone studying water treatment and distribution systems, as it helps in identifying and mitigating corrosion-related issues that can affect water quality and pipe integrity.
