Yes, carbonated water has a lower pH than regular water, meaning it is more acidic.
pH Comparison:
- Regular water: pH = 7 (neutral)
- Carbonated water: pH = 3 to 4 (acidic)
Reason:
- Carbon dioxide (CO₂) dissolves in water
- Forms carbonic acid (H₂CO₃)
- Releases H⁺ ions, lowering the pH
Is it harmful?
- Generally safe for consumption
- Much less acidic than strong acids
- Does not significantly harm the body when consumed in moderation
Key Takeaway:
Carbonated water is more acidic than regular water due to the formation of carbonic acid, which lowers its pH.
