In electrolysis, what is the purpose of the cathode?

  1. To extract moisture

  2. To provide heat

  3. To deliver a positive charge

  4. To facilitate hair removal

The correct answer is: To facilitate hair removal

In electrolysis, the cathode plays a crucial role in facilitating hair removal. The cathode is the electrode through which the electric current flows into the electrolyte solution, which in this context is the area surrounding the hair follicle. When the current reaches the hair follicle, it causes the breakdown of the follicle's structure, leading to the destruction of the hair root. This is essential for effective hair removal because it ensures that the hair cannot regrow after treatment. The operation of the cathode is fundamental to the electrolysis process, as it allows for the electron transfer necessary to create chemical reactions at the hair follicle, ultimately leading to permanent hair removal. Therefore, its role is directly tied to the primary aim of electrolysis in a cosmetic context, which is to remove unwanted hair.
