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-.
Sodium hydroxide (NaOH) is a base while vinegar, which is mainly made up of acetic acid (CH3COOH) is an acid. An acid and a base react together to neutralize each other and produce a salt. So the two react to produce water, sodium acetate, and carbon dioxide gas.
