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-.
When we look at the list of bases we see a pattern, omiting ammonia for the moment, that bases contain a metal atom and hydroxide ion. Formula Name O2N(OH)(aq) nitric acid O2S(OH)2(aq) sulfuric acid OP(OH)3(aq) phosphoric acid O3Cl(OH)(aq) perchloric acid OC(OH)2(aq) carbonic acid.
