Naming Acids, Bases, and Salts
POLYATOMIC IONS
NH4+______________
NO3-______________
SO4-2______________
PO4-3______________
NO2- ______________
SO3-2______________
PO3-3______________
ClO3-______________
CO3-2______________
ClO2- ______________
OH- ______________
C2H3O2-______________
SALTS
Formula: YX
Y = cation, but not H+
X = anion, but not OH-
1. Salts are ionic compounds. To name an ionic compound say the name of the cation first, followed by the
anion. The anion will end in -ide or -ate. (-ate means it contains oxygen)
2. Practice:
MgCl2
_____________________________
LiBr
_____________________________
Al(NO3)3 _____________________________
BASES
K2SO4
_____________________________
BaCO3
_____________________________
NH4Cl
_____________________________
ZnI2
_____________________________
Ag2SO4
_____________________________
KClO3
_____________________________
NH4F
_____________________________
Formula: YOH
Y = cation
OH- = hydroxide ion
1. You should already know how to name most bases. Remember (OH-) is hydroxide. The compound NaOH,
for example is ________________________. Ca(OH)2 is named _______________________.
2. Practice:
Mg(OH) 2 _____________________
LiOH _____________________
Al(OH) 3 _____________________
NH4OH _____________________
3. One exception to this that requires memorization: NH3 is __________________. It’s a BASE!
ACIDS
Formula: H X
H+ = hydrogen ion
X = anion
4. BINARY ACIDS RULE says: If the anion ends in –ide,
hydro ______________ic acid
Example:
HCl hydrochloric acid
Practice:
HBr _____________________
HI _____________________
HF ______________________
5. TERNARY ACIDS RULE 1 says: If the polyatomic anion ends in –ate
Hydro ______________ic acid
Example:
HClO3
chloric acid
Practice:
HNO3 _____________________ H2CO3 _____________________
H2SO4 _____________________ HC2H3O2 ______________________
H3PO4 ______________________
6. TERNARY RULE 2 says: If the polyatomic anion ends in –ite
Hydro ______________ous acid
H2SO3 ______________________ H2ClO2 ____________________
H3PO3 ______________________ HNO2 ______________________
