Water that has been subjected to ionization, typically through electrolysis, undergoes a modification of its pH level. This process separates the liquid into acidic and alkaline streams. The resulting alkaline stream, often referred to as alkaline water, contains a higher concentration of hydroxide ions (OH-) than hydrogen ions (H+), resulting in a pH greater than 7. For example, tap water may be processed to increase its alkalinity.
The potential benefits and importance of consuming water treated in this manner are areas of ongoing research. Proponents suggest it can neutralize acidity in the body and provide enhanced hydration. Historically, the technology to create such water has been utilized in medical settings and is now increasingly common for domestic use. However, scientific consensus regarding the extent and nature of these purported benefits is still developing.
