Acid - Base Neutralization Reactions
A key characteristic of both acids and bases is that they react in a way to neutralize or remove the properties of the other. These are double replacement reactions and the general way to write such a reaction is as follows:

Definition: A salt is the substance formed when the cation of the base combines with the anion of the acid. These substance generally have a neutral pH.

Theory behind neutralization
The following link reviews the writing of nonionic total ionic and net ionic equations.
How does the adding of an acid to a base neutralize the properties of the base?
Chemists can illustrate how acids neutralize bases using a net ionic equation. The following flash presentation illustrates the writing of the net ionic equation for the above reaction. The ideas presented here were first proposed by Svante Arrhenius at the turn of the 20 th century
