What is the name of the negative pole used in electrolysis?

In electrolysis, the negative pole is referred to as the cathode. During the process of electrolysis, an electric current is passed through an electrolyte solution, causing a chemical reaction. The cathode is the electrode where reduction occurs, meaning that it is where electrons are gained. This is crucial in electrolysis because it is at the cathode that ions in the electrolyte are reduced to their neutral form.

In the context of electrolysis for hair removal, the cathode plays a pivotal role in delivering the current to destroy hair follicles. Understanding the function of the cathode enhances the overall knowledge of electrolysis and its applications in cosmetology, particularly in the field of electrology. This is essential knowledge for professionals, as it directly relates to how effective treatments are carried out.

The other terms provided in the options do not serve as the negative pole in electrolysis. The anode, for example, is the positive electrode where oxidation occurs. On the other hand, a transformer does not refer to an electrode but rather a device that modifies electrical voltage. The term ground usually pertains to safety in electrical systems and does not designate a specific pole within the electrolysis process. Hence, understanding the role of the cathode as the negative pole is fundamental
