The Dissociation of an Acid

HCl (g) -> H+(aq) + Cl-(aq)

but, the real dissociation produces a hydronium ion (a hydrated proton)

HCl(g) + H2O(l) -> H3O+(aq) + Cl-(aq)

Acid

a substance which donates a proton to another substance

Base

a substance which accepts a proton from another substance

Amphiprotic

a substance that can either act as an acid or a base

Conjugate Acid/Base Pairs

a pair of chemical species which differ by only one proton

conjugate acid has the extra proton

conjugate base lacks the extra proton
