Binary/Ternary Acid Nomenclature

Binary/Ternary Acid Nomenclature. Binary Acids are acids made of two components. Hydrogen and, A single nonmetal (F, S, Cl, Se, Br, and I) Ternary Acids are acids made of two components. Hydrogen and, A polyatomic ion Acids act as molecular and ionic compounds.

  1. Binary/Ternary Acid Nomenclature Binary Acids are acids made of two components. Hydrogen and, A single nonmetal (F, S, Cl, Se, Br, and I) Ternary Acids are acids made of two components. Hydrogen and, A polyatomic ion Acids act as molecular and ionic compounds. When dissolved in water, acids ionize or, in some cases, dissociate.

  2. Binary Acid Formulae HCl This ishydrochloric acid. Formula Structure Elements present (always starts with hydrogen) Subscripts* (shows how much of each element) * If no subscript is present it means that there is only one atom of that element This is a molecule of a molecular compound.

  3. Binary Acid Nomenclature Naming those featuring a single nonmetal… Write “hydro” immediately followed by the second element, the nonmetal. Change the ending of the second element to -ic. Had this been a normal molecular formulae the ending would have been –ide… It maybe helpful to think “Change –ide to –ic.” Write the word “acid” Example: HCl becomes hydrochlorine hydrochloric hydrochloric acid

  4. Ternary Acid Formulae HNO2 This isnitrous acid. Formula Structure Elements present (always starts with hydrogen) Subscripts* (shows how much of each element) * If no subscript is present it means that there is only one atom of that element This is a molecule of a molecular compound.

  5. Binary Acid Nomenclature Naming those featuring a polyatomic ion… Write the name of the polyatomic ion. Change the ending of the polyatomic ion… -ate turns to -ic. “Change –ate to –ic.” -ite turns to –ous. “Change –ite to –ous.” Write the word “acid” Example: HNO2 becomes nitrous acid nitrite nitrous

  6. Binary Acid Formulae Cl- NO3- SO42- F- S2- BO33- PO43- I- ClO3- Br- HPO42- HF hydrofluoric acid H2S hydrosulfuric acid HCl hydrochloric acid H3PO4 phosphoric acid HClO3 chloric acid HI hydroiodic acid H2SO4 sulfuric acid H3PO4 phosphoric acid HBr hydrobromic acid H3BO3 boric acid HNO3 nitric acid H+
