1. 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) Preview of some acids: FormulaSalt/gasFormulaaqueous HClhydrogen chlorideHCl (aq) hydrochloric acid HFhydrogen fluorideHF (aq) hydrofluoric acid HNO 3 hydrogen nitrateHNO 3 (aq) nitric acid HC 2 H 3 O 2 hydrogen acetateHC 2 H 3 O 2 (aq) acetic acid HClO 4 hydrogen perchlorate HClO 4 (aq)perchloric acid NOTE: they all have the generic formula H-anion
