1. Acid Nomenclature
Acids are an important class of hydrogen-containing compounds.
For now, an acid is defined as a substance that produces hydrogen ions (H+) when dissolved in water.
There are two common types of acids:
binary acids
oxyacids

2. Binary Acids a compound formed between: Rules for naming binary acids:
hydrogen and a monatomic anion –OR–
hydrogen and a polyatomic ion that does not contain oxygen
Rules for naming binary acids:
1. Begin with the prefix hydro-
2. Add the name (or root) of the nonmetallic anion
3. Add the suffix –ic and the word acid

3. Binary Acids hydro + anion nonmetal root + ic + acid example: HCl
hydrochloric acid
example: H2S
hydrosulfuric acid

4. ate-ic-ite-ous Oxyacids a compound formed between:
hydrogen and a polyatomic ion that contains oxygen
Rules for naming oxyacids:
1. Name the polyatomic ion
2. Change “-ate” to -ic ; “-ite” to –ous
3. Add the word acid
4. The oxoanion prefixes “per-” and “hypo-” remain
ate-ic-ite-ous

5. Oxyacids example: HBrO4 perbromic acid HBrO3 bromic acid HBrO2
bromous acid
hypobromous acid
HBrO

6. Acid Nomenclature Name the following compounds: H2SO4 sulfuric acid
hydrophosphoric acid
H3P
perchloric acid
HClO4

7. Acid Nomenclature Write formulas for the following acids:
hydrofluoric acid H+ F- HF
phosphoric acid H+
PO43-
H3PO4
H2SO3
sulfurous acid H+
SO32-

8. Base Nomenclature
Bases are another important class of chemical compounds.
For now, a base is defined as a substance that produces hydroxide ions (OH-) when dissolved in water.
Rules for naming bases: “same as usual”

9. Salt Nomenclature
Salts are another important class of chemical compounds.
A salt is an ionic compound composed of a cation from a base and an anion from an acid.
Rules for naming salts: “same as usual”

10. Acid, Base, & Salt Nomenclature
Identify the following as an acid, base or salt; then, name the compound:
HNO3
acid
nitric acid
NaOH
base
sodium hydroxide
NaNO3
salt
sodium nitrate
Ca(OH)2
base
calcium hydroxide
H2S
acid
hydrosulfuric acid
