CHEMICAL FORMULAS AND NAMES CONTINUED

 

BINARY ACIDS AND OXYACIDS  

 

Binary Acids: contain H atoms (which are released as H⁺ when the acid is dissolved) and a simple anion such as Cl^- or Br ^- or S^2- 

example: HCl → hydrochloric acid , H₂S → hydrosulfuric acid

 

naming binary acids calls for adding a prefix (hydro-), a suffix (-ic), and the term acid to the root name of the non-metal element (the anion)

 example: HF→ hydrofluoric acid  

 

Oxyacids: contain H atoms (which are released as H⁺ when the acid is dissolved) and an oxyanion such as SO₄^2- or NO₃^-

example:

 

H₂SO₄ →sulfuric acid  oxyanion name: sulfate

H₂SO₃ → sulfurous acid oxyanion name: sulfite

HC₂H₃O₂ → acetic acid  oxyanion name: acetate

 

naming oxyacids calls for adding a suffix (-ic or -ous), and the term acid to the root name of the oxyanion

example:HNO₃ → nitric acid  oxyanion name: nitrate
 HNO₂  → nitrous acid oxyanion name: nitrite

 

notice that when the oxyanion name ends in -ate, the acid name ends in -ic and when the oxyanion name ends in -ite, the acid name ends in -ous
