Acid nomenclature.notebook February 02, 2017 Writing Acid Formulas/Naming acids formula starts with "H" nameends in "acid" Balance the overall charge to zero... (like ionic criss cross) +1 3 All acids start with H+1 H PO4 H3PO4 Identify the acid: cation is always H+ use the anion to name it 3 ways to name: 1. binary acids ("bi" = "2") or nonoxy acid H+ and one other element anion ends in ide HCl Cl1 chloride hydro_____ic acid HF F1 fluoride hydro_____ic acid H2S S2 sulfide hydro_____ic acid 3 H3N N nitride hydro_____ic acid Binary rule: hydrostemic acid use stem from anion 2. Oxyacid acids contain oxygen Again, look at the anion 1 HNO3 NO3 nitrate _____ic acid 2 _______ic acid H2SO4 SO4 sulfate 3 _______ic acid H3PO4 PO4 phosphate oxyacid rule #1: Oxyacid rule #1: if anion ends in ate, use stemic acid I ate something icky in the cafeteria 1 HNO2 NO2 nitrite _____ous acid 2 _______ous acid H2SO3 SO3 sulfite 3 _______ous acid H3PO3 PO3 phosphite oxyacid rule #2: if anion ends in ite, use stemous acid 1 Acid nomenclature.notebook February 02, 2017 acid nomenclature: (review) Acids binary (nonoxy) oxyacid ______ide ______ite ______ate hydro______ic acid _______ous acid _______ic acid 2 Acid nomenclature.notebook February 02, 2017 Naming Acids Anion Ending Acid Name Binary @ ide hydro(stem)ic acid ate (stem) ic acid Oxyacid/ Ternary ite (stem) ous acid An easy way to remember which goes with which… “In the cafeteria, you ATE something ICky” 3 Acid nomenclature.notebook February 02, 2017 Naming Acids underline stem name of anion rule acid name bromide HBr binary: Br1 hydrostemic acid hydrobromic acid oxyacid: H2CO3 carbonate 2 Stemic acid carbonic acid CO3 sulfite oxyacid: sulfurous acid H2SO3 Stemous acid 2 (note: not exact stem) SO3 4 Acid nomenclature.notebook February 02, 2017 Formula Anion Anion Acid Name name HF HCl hydrobromic acid HI hydrosulfuric acid HNO3 acetic acid H2SO4 carbonic acid H3PO4 hypochlorous acid HClO2 chloric acid HClO4 iodic acid HNO2 H2SO3 5 Acid nomenclature.notebook February 02, 2017 Formula Anion Anion Acid Name name HF F is fluoride hydrofluoric acid HCl Cl is chloride hydrochloric acid HBr Br is bromide hydrobromic acid HI I is iodide hydriodic acid H S 2 S2 is sulfide hydrosulfuric acid HNO 3 NO is 3 nitrate nitric acid HC H O 2 3 2 C H O is 2 3 2 acetate acetic acid H SO 2 4 SO 2 is sulfuric acid 4 sulfate H CO 2 3 CO 2 is 3 carbonate carbonic acid H PO 3 4 PO 3 is 4 phosphate phosphoric acid HClO ClO¯ is hypochlorite hypochlorous acid HClO 2 ClO ¯ is 2 chlorite chlorous acid HClO 3 ClO ¯ is 3 chlorate chloric acid HClO 4 ClO ¯ is 4 perchlorate perchloric acid HIO 3 IO ¯ is 3 iodate iodic acid HNO 2 NO ¯ is 2 nitrite nitrous acid H SO 2 3 SO 2 is 3 sulfite sulfurous acid 6 Acid nomenclature.notebook February 02, 2017 Review: What indicates an acid: in the name? in the formula?
