1. Naming Acids and Bases

2. Acids
Arrhenius definition: Break apart (dissociate) to yield hydrogen ions (H+) in water (aqueous) solutions
Look for H at the beginning of a compound!
HCl H+ + Cl-
HNO H+ + NO3-
H2SO H+ + HSO4 -
H2O
H2O
H2O

3. Naming Acids Name or give the formula of the following acids: H2SO4
Anion Ending
Acid Name
-ide
hydro-(stem)-ic acid
-ite
(stem)-ous acid
-ate
(stem)-ic acid
Name or give the formula of the following acids:
H2SO4
Oxalic acid HF

4. Bases
Arrhenius definition: Break apart (dissociate) to yield hydroxide ions (OH-) in water (aqueous) solutions
Look for OH ending!
NaOH Na+ + OH-
KOH K+ + OH-
H2O
H2O

5. Naming Bases Cation name + hydroxide NaOH sodium hydroxide Ca(OH)2
calcium hydroxide
NH4OH
ammonium hydroxide
Cation name + hydroxide

6. Naming Bases Name the following bases: Ba(OH)2 KOH Al(OH)3
Cation name + hydroxide

7. More Naming Practice H3PO4 Nitrous acid Mg(OH)2 Hydrobromic acid
Name the following acids/bases or write their formula:
H3PO4
Nitrous acid
Mg(OH)2
Hydrobromic acid
Lithium hydroxide
H2S
Anion Ending
Acid Name
-ide
hydro-(stem)-ic acid
-ite
(stem)-ous acid
-ate
(stem)-ic acid

8. Even More Naming Practice!
Identify whether the following are acids or bases. Then name them!
Ba(OH)2
2. H2S
3. CH3COOH
4. Fe(OH)2
5. HClO2
Anion Ending
Acid Name
-ide
hydro-(stem)-ic acid
-ite
(stem)-ous acid
-ate
(stem)-ic acid
