WebAny acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid. HC 2 H 3 O 2 is an example of a weak acid: HC 2 H 3 O 2 → H + (aq) + C 2 H 3 O 2− (aq) (~5%) Because this reaction does not go 100% to completion, it is more appropriate to write it as an equilibrium: WebAn acid which is strong in water may be weak in a less basic solvent, and an acid which is weak in water may be strong in a more basic solvent.
