Hydronium ion

When H2O becomes H3O, where does the oxygen pick up a hydrogen? Does it take it from a nearby oxygen?

The reaction we did in class was HCl + H2O --> H3O+ + Cl-
The extra H comes from the HCl since HCl dissociates in H2O.

In an acid base reaction, the bronsted acid will donate the H+ to the bronsted base.

A hydrogen atom will pick up the H+ of the salt, thus creating H3O+

I think that in the cases that acids dissolve in water, the actual reason why acids lower the pH is that they easily release a hydrogen atom that is then taken by water to form a hydronium ion, lowering the pH of the solution.

When an acid is dissolved in water, the hydrogen will dissociate and bond with a water molecule, forming H3O
