Because of its small size and large charge density, however, the free proton in aqueous solution is unstable and will immediately combine with water to form the hydronium ion (H 3 O +; Fig. 1a).

As this positively charged ion–which is called hydronium, or H 3 O + –moves through water, those bonds break and shift.

The recombination of hydronium and hydroxide ions following water ionization is one of the most fundamental processes determining the pH of water. The neutralization step once the solvated ions are in ...
