Naming Bases
• Bases are ionic compounds composed of a) metallic or positively charged ions
& b) negatively charged hydroxide ion (OH-)
Rule for naming: add the word “hydroxide” to the name of the positive ionEx) NaOH KOH Ca(OH)2

SALTS
Salts are usually described as ionic solids, made up of a positive metallic ion & a negative non-metallic ion joined together by an ionic bond. Salts may be prepared through the neutralization reaction between an acid & a base. acid + base salt + water
Ex) HCl + NaOH NaCl + H2O

Naming Salts:
The negative ion of a salt is named by using a stem, the name of the acid with a different ending.The pattern is as follows:ending of name of acid ending of negative ion
“ic” becomes ate“ous” becomes ite
Ex) 1. HBrO4 + NaOH NaBrO4 + H2O
perbromic acid sodium perbromate

2. HBrO3 + NaOH NaBrO3 + H2O bromic acid sodium bromate
3. HBrO2 + NaOH NaBrO2 + H2O
bromous acid sodium bromite
4. HBrO + NaOH NaBrO + H2O hypobromous acid sodium hypobromite
Name the parent acid & base of each salt:
Negative ion – from acid Positive ion – from base
SALT PARENT ACID PARENT BASE
KNO3
Na2SO4
LiClO
NaFO4

Salts of Diprotic Acids (H2SO4 & H2CO3)
Salt with 1 hydrogen are sometimes indicated by the use of the prefix “bi”. Ex) NaHSO4 sodium bisulfate or sodium hydrogen sulfate
Salts of Polyprotic Acids (H3PO4)
Prefixes may be used to indicate the number of acid hydrogens remaining.Ex) H3PO4 - acid parent phosphoric acid
NaH2PO4 sodium dihydrogen phosphate
Na2HPO4 sodium monohydrogen phosphate
Na3HPO4 sodium phosphate

• NOTE: the charge of the negative ion is determined by the number of protons (H+) lost.
CO32- lost 2H+ = H2CO3
PO43- lost 3H+ = H3PO4
NO2- lost 1H+ = HNO2
Sample Problems: Name the following salts.1. NaFO4 6. calcium hyponitrite
2. KClO2
3. LiBrO 7. iron (III) percarbonate
4. NaClO3
5. HNO
