The negative plate in an electrochemical cell is known as what?

In an electrochemical cell, the negative plate is referred to as the cathode. This terminology is essential for understanding the role of each component in the electrochemical process. During the operation of the cell, reduction reactions occur at the cathode, meaning that it is the site where electrons are gained.

To further clarify the context: in electrochemistry, the anode is the positive plate where oxidation occurs, while the cathode is the negative plate where reduction takes place. The difference in charge between these two plates is crucial to the flow of current within the cell, as electrons flow from the anode to the cathode.

Understanding the functions of these components helps in grasping the principles of how electrochemical cells produce electric energy. The term "battery" refers to a collection of electrochemical cells, rather than a specific component, which is why it does not fit the description of the negative plate in the context of this question. Similarly, while "electrode" is a broader term that can refer to either the anode or cathode, it does not specifically identify the negative plate.
