					           Salts and Acid-Base Neutralization
In chemistry, the term salt refers to the ionic product produced when any
base reacts with any acid. The salt gets its cation from the base and its
anion (anything but OH-) from the acid, e.g.
        HCℓ(aq) + NaOH(aq) → H2O(l) + NaCℓ(aq) (table salt)
        H2SO4(aq) + 2 LiOH(aq) → 2 H2O(l) + Li2SO4(aq)
             H3PO4(aq) + 3 NH3(aq) → (NH4)3PO4(aq)                  salts
                 HCℓ(g) + NH3(g) → NH4Cℓ(s)
     CH3COOH(aq) + CH3NH2(aq) → CH3COOCH3NH3(aq)

Acid/Base Neutralization
An acid-base neutralization reaction is the chemical reaction between
any acid and any base in which both the starting acid and starting base
are entirely consumed. That is, all the protons that can be removed
from the acid have been removed; all of the proton removal capacity of
the base has been satisfied.
The most commonly encountered neutralization reactions occur in liquid
solution and involve hydroxide bases, hence the definition in the text,
page 262. However, NH3(aq) + HCl(aq)  NH4Cl(aq) is an acid/base
neutralization reaction, despite the text book’s definition.
