The Basics
pH Definition.
pH means potentiality of hydrogen. The pH unit value represents the concentration of hydrogen ions in the water.
The Scale
Key Concepts.
0-6
Acidic Solutions
Higher concentrations of hydrogen (H+) ions and lower pH values.
7
Neutral pH
Water has an equal number of hydrogen ions (H+) and hydroxyl ions (OH-).
8-14
Alkaline Solutions
Lower concentrations of hydrogen ions and higher pH values.
Logarithmic Scale
Mathematics.
Each pH unit represents a tenfold difference between hydrogen ion (H+) and hydroxyl ion (OH-) concentrations.
- At a pH of 8, water has a 10x greater concentration of OH- ions than H+ ions.
- At a pH of 9, water has a 100x greater concentration of OH- ions than H+ ions.
Ionized Water
Alkaline.
pH Range: 8-10
Properties: Higher concentration of OH- ions
Benefits: Antioxidant-rich, better hydration
Source: Cathode (-) electrode stream
Ionized Water
Acidic.
pH Range: 4-6
Properties: Higher concentration of H+ ions
Uses: Cleaning, disinfection, skin care
Source: Anode (+) electrode stream
