WebVideo transcript. - [Instructor] A strong acid is an acid that ionizes 100% in solution. For example, hydrochloric acid, HCl, as a strong acid it donates a proton to water, H2O, to form the hydronium ion, H3O plus, and the conjugate base to HCl which is the chloride anion, Cl minus. In reality, this reaction reaches an equilibrium.
