What is the negative pole used during electrolysis known as?

During electrolysis, the negative pole is referred to as the cathode. In the process, the cathode is the site where reduction occurs, meaning that it is where electrons are gained by ions. This is essential for the electrolysis process, as it allows for the separation of compounds or the deposition of materials.

In the context of electrolysis, ions are attracted to the cathode due to their charge; negatively charged anions move towards the positive electrode (anode), while positively charged cations move towards the cathode. The ability of the cathode to attract cations and facilitate reactions is crucial for applications in electrolysis, such as in electroplating or the production of chemical compounds. Understanding the role of the cathode helps in grasping the overall mechanisms and outcomes of electrolytic processes.
