Hydrogen peroxide is a weak acid. Generally, acids distinguishable by the hydrogen proton, while bases are generally anything with a hydroxide. For instance, hydrochloric acid, or HCl, can be distinguished by the H+ bonded with Cl-. NaOH on the other hand, is a bond between Na+ and OH-.
Every single one! Examples of strong Arrhenius acids are Hydrochloric acid (HCl), Sulfuric acid (H2SO4) and Hydrobromic acid (HBr). Some strong Arrhenius bases include Sodium hydroxide (NaOH), Potassium hydroxide (KOH) and Lithium hydroxide (LiOH). On the other hand weak acids and bases dissociate much less than 100% in solution. Instead, only a small fraction of the acid or base compound that goes into solution breaks apart into its constituent ions. Common weak Arrhenius acids include vinegar, or acetic acid (HC2H3O2), and phosphoric acid (H3PO4).
