WebAcids provide the H + ion; bases provide the OH - ion; and these ions combine to form water. H + ( aq) + OH - ( aq ) H 2 O ( l) The Arrhenius theory has several disadvantages. It can be applied only to reactions that occur in water because it defines acids and bases in terms of what happens when compounds dissolve in water. WebAcids and bases can be defined via three different theories. The Arrhenius theory of acids and bases states that “an acid generates H + ions in a solution whereas a base …
