# How are salts formed from acids and bases?

Jun 8, 2016

It lies in the definition of acid and bases.

#### Explanation:

An acid is a compound that breaks apart into ${H}^{+}$ and some other anion when it dissolves in water.

For instance:

HCl(aq.) → H+(aq.) + Cl-(aq.)

HBr(aq.) → H+(aq.) + Br-(aq.)

A base is a compound that breaks apart into OH- and some other cation when it dissolves in water.

For instance:

Al(OH)3(aq.) → Al+3(aq.) + 3OH-(aq.)
