Acids and Bases. Atoms can gain or lose electrons in order to form ions in a process called ionization (compounds formed in this way are called ionic compounds).When ionic compounds dissolve in water, their ions separate from one another in a process called dissociation.One interesting feature of water and many other covalent compounds is that they too can dissociate into ions.cids and Bases.
