The generic formula for an acid is HA (aq) ACIDS In its simplest form, an inorganic acid is defined as a hydrogen salt dissolved in water. By this definition a simple inorganic acid exists in the aqueous state. The generic formula for an acid is HA (aq) NOTE: they all have the generic formula H-anion Preview of some acids: Formula Salt/gas Formula aqueous HCl hydrogen chloride HCl(aq) hydrochloric acid HF hydrogen fluoride HF (aq) hydrofluoric acid HNO3 hydrogen nitrate HNO3 (aq) nitric acid HC2H3O2 hydrogen acetate HC2H3O2 (aq) acetic acid HClO4 hydrogen perchlorate HClO4 (aq) perchloric acid
