This document discusses nomenclature rules for binary compounds, binary bases and acids, and oxoacids. It explains that binary compounds contain two elements, binary bases contain OH- or have hydroxide in their name, and binary acids form when a hydrogen atom bonds to another element and dissolves in water. Rules are provided for naming binary acids based on the elements present. Oxoacids contain oxygen, hydrogen, and another element, and have suffixes that indicate the number of oxygen atoms such as -ous, -ic, and -ic. Examples are given for common oxoacid ions and their names.

1. NOMENCLATURE REVIEW

2. Binary Compounds
• A compound with only 2 different elements
ex. HBr, NaCl, CO2

3. MgI2

4. SiC

5. NaCl

6. Lithium nitride

7. Calcium oxide

8. ACID BASE
NOMENCLATURE

9. Binary Bases
• They have OH- in their formula or hydroxide in their name.
Exception: Ammonia (NH3)

10. NaOH

11. Ba(OH)2

12. Fe(OH)3

13. Calcium hydroxide

14. Aluminum hydroxide

15. Ammonium hydroxide

16. Binary Acids
• When a hydrogen atom is covalently bonded to another
atom
• the substance is an acid when it is dissolved in water.
Ex. HF(aq)  hydrofluoric acid
(aq) = aqueous = dissolved in water
Do not omit this!!

17. Rules for Naming Binary Acids
• 1. Write hydro as a prefix to the name of the first
element.
• 2. Add an "ic" ending to the name of the second
element.
• 3. Write the word "acid" after leaving a space.
Ex. H2S(aq)  hydrosulfuric acid

18. H & F

19. H & Cl

20. H & l

21. H & Br

22. H & S

23. H & S

24. Oxoacids
• Some acids that contain oxygen are called
oxoacids
• They are made of oxygen, hydrogen and some other
element, almost always a non-metal
• They have special suffixes that depend on the
number of oxygen atoms in the acid
• There is little to do but memorize them.
