In the galvanic modality, which pole is responsible for producing sodium hydroxide?

In the galvanic modality, the negative pole is responsible for producing sodium hydroxide during the electrolysis process. This occurs because, at the negative electrode (cathode), a chemical reaction takes place where water and salts are decomposed. Sodium ions migrate toward the negative pole and combine with hydroxide ions produced through the electrolysis of water, resulting in the formation of sodium hydroxide.

The process occurs as a direct result of the electrochemical reactions that take place during galvanic treatments. As negative ions gather at the cathode, they facilitate the breakdown of water molecules, leading to an increase in the pH of the solution, which is indicative of strong alkaline properties typical of sodium hydroxide.

Understanding this is vital for effective practice in electrology, as the role of the poles can influence treatments and their outcomes on the skin.
