When a protic acid is added to water, it releases a hydrogen ion (H+) (also called a proton because a hydrogen atom missing one electron is nothing but a proton!). However, H+ will not stay a free ion, and instead immediately combines with a nearby water molecule (H2O) to form the hydronium ion, H3O+. For example, when hydrochloric acid (HCl) is added to water, the following reaction occurs: HCl + H2O --> H+ + Cl- + H2O --> H3O+ + Cl- Note that the Cl- is stable by itself and does not combine with anything else. This is because it is much larger than H+ (remember, H+ is just a single proton), and that makes Cl- more stable (they both have a single charge, but because Cl- is larger, the charge density is lower and it is the charge density that matters -- the sign, + or -, makes no difference).
