Unformatted text preview: Unit 9 Acids and Bases An Acid is an aqueous solution of a hydrogen compound. HCl H 2 SO 4 H 2 SO 3 H 2 S hydrochloric acid sulfuric acid sulfurous acid hydrosulfuric acid Rules for Naming Acids Acids are aqueous solutions of hydrogen compounds Binary Acids (H A X B ) Are always named as HYDRO+(root of anion)+IC ACID HCl H 2 S hydrochloric acid hydrosulfuric acid hydroiodic acid hydrosulfuric acid H + I 1- H + S 2- HI H 2 S Ternary Acids (H A XY B ) Are always named after the polyatomic anion. If the polyatomic anions name ends in -ate, then the acids name ends in -ic. If the polyatomic anions name ends in -ite, then the acids name ends in -ous. H 2 SO 4 H 2 SO 3 SO 4 2- sulfate SO 3 2- sulfite sulfuric acid sulfurous acid nitric acid nitrous acid H + NO 3 1- H + NO 2 1- HNO 3 HNO 2 Common Acids Name Formula Common Name Properties/Uses sulfuric acid H 2 SO 4 battery acid most commonly produced industrial chemical in the world nitric acid HNO 3 volatile, unstable liquid; used in explosives; turns proteins yellow phosphoric acid H 3 PO 4 used in fertilizers, animal feed, soda, detergents hydrochloric acid HCl muriatic acid, stomach acid used in steel making, food processing; as an industrial intermediate acetic acid HC 2 H 3 O 2 or CH 3 COOH vinegar food industry; fungicide; plastics Many bases contain the polyatomic ion hydroxide (OH-).
