How to do acid base neutralization reactions work?

1 Answer

Acids are defined as proton donors and bases as proton acceptors. Neutralisation is when both are in equilibrium.

Explanation:

A proton is nothing more than an ionized hydrogen atom H+

Most common acids are characterized by the hydronium ion, which looks like H3O+. This can donate a proton and turn into water:

H3O+H2O+H+

A common base has the hydroxide ion OH

And these combine: H3O++OH2H2O
Or more commonly: H++OHH2O

There are many more acid-base reactions, like between acid and metal oxide, or between base and non-metal oxide, but the above is the one that is most usually called an acid-base reaction.
