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-.
Acids are electrolytes Bases are electrolytes Acids react with carbonates to produce a salt, water and CO 2 Bases feel slippery Monoprotic acids HNO 3 â nitric acid HCl â hydrochloric acid HC 2H 3O 2 â acetic acid Diprotic acid H 2SO 4 â sulfuric acid Triprotic acid H 3PO 4 â phosphoric acid Acids react with active metals to produce hydrogen Examples of bases: LiOH NaOH KOH Mg(OH) 2 Ca(OH) 2 NH 4OH Reaction of an acid with a base (neutralization) always produces a salt and water: Acid Base Salt water
