H3O+ ions which form when an acid dissolves in water and H+ ions interact with water.

Neutralization
chemical reaction that occurs when H3O+ ions from an acid react with OH- ions from a base to produce water molecules.
pH
a measure of the concentration of hydronium ions in a solution using a scale ranging from 0 to 14 with 0 being the most acidic and 14 begin the most basic.
