Does ionized water restore body acid and alkaline balance?

No. Ionized water and the devices that supposedly make it are scams that are widely perpetuated on the internet. There is a small degree of pseudoscience that initiates the discussion, then it degrades into completely unsubstantiated and, in most instances, scientifically impossible nonsense. Acid-base balance is tightly controlled in various portions of the body, whether digestion, absorption or blood pH. Water exists as H20 and H+ and –OH ions. It is in a constant state of flux between the bound and ionized form, whereas in pure water, the pH settles at neutral or 7. Dissolved minerals such as Na+, Mg+ or Cl- can ionize the water, but disassociated water ions will have a tendency to bind with them, buffering significant changes in pH. The numerous health claims made by sites selling water ionization devices lack scientific credibility and are, frankly, illegal. The science behind water and acid-base theory conflict with the information these sites dispense.
