Acid Overview

An acid simply defines as a substance in water solutions dissociate yielding hydrogens ions as only a positive ions. Some acids dissociate in one step yield one hydrogen ion called monobasic acid. Here is the example monobasic acid.














Others acid dissociate yield two or more hydrogen ions through two dissociation steps or more called polybasic acid.



 


Actually, in a aqueous solution, hydrogen ions doesn't exist. This proton combine with a water molecule form a hydronium ions by coordination covalent bond using a free pair electron from oxygen of the water molecule.
