Naming Acids and Bases:
At the conclusion of our time together, you
should be able to:
1. List 3 properties of acids and bases
2. Name a binary and oxy- (ternary) acid
3. Name a base
6 Types Of Chemical Compounds
•Binary ionic
- metal ion – nonmetal ion
•Binary molecular - two nonmetals
•Ternary ionic
- at least one ion is a
polyatomic ion
•Binary acid
- H – nonmetal
•Ternary acid
- H – Polyatomic ion
•Base
- metal ion – OH
Acids & Bases

Their Properties
Properties of Acids
Taste sour
 Itchy on skin, will burn if concentrated
 Turns Blue litmus paper Red
 Red litmus paper stays Red
Reacts with Base - Neutralization:
Acid + Base  Salt + Water
Ex: Vinegar, Citrus Fruit

Properties of Bases
Taste Bitter
 Feel Slippery
 Turns Red litmus paper Blue
 Blue litmus paper stays Blue
Reacts with Acid - Neutralization:
Acid + Base  Salt + Water
Ex: Soap, Milk of Magnesia, Most Cleaners

The Fourth Category Of Compounds Is
Binary Acids.
•These compounds begin with hydrogen since they are
“acids”.
•Attached to the hydrogen is a nonmetal ion
•Hydrogen – nonmetal ion
What are Binary Acids?
Binary means two elements
Naming
All binary acids follow the pattern as shown next:
Naming Binary Acids
Contain “H” and one other element (nonmetal)
To Name:
Hydro + second element name shortened (stem)
+ ic + acid
Ex: HCl = Hydro chlorine – ine + ic acid
Hydrochloric acid
HF =
Hydroflouric acid


The Fifth Category Of Compounds Is Ternary
Acids.
•These compounds begin with hydrogen since they are
“acids”.
•Attached to the hydrogen is a polyatomic ion
•Hydrogen – polyatomic ion
New Element On The Periodic Table
Element:
Woman
Symbol:
Xx
Atomic Mass:
120 (More Or Less)
Naming Ternary (Oxy)Acids (cont.)
Contain “H”, “O” and one more element
To Name:
Polyatomic ion “ate”  “ic” + acid
Ex: HNO3 = Nitr-ate  ic + acid
Nitric acid
HClO3 =
Chloric acid
 An easy way to remember which goes with
which…
 “In the cafeteria, you ATE something ICky”

Naming Acids (cont.)
If the acid has one more oxygen than the base acid,
the naming goes as followed:
To Name:
Per + Polyatomic ion “ate”  “ic” + acid
Ex: HNO4 = Per + Nitr-ate  ic + acid
Pernitric acid
H2SO5 =
Persulfuric acid

Naming Acids (cont.)
If the acid has one less oxygen than the base acid,
the naming goes as followed:
To Name:
Polyatomic ion “ite”  “ous” + acid
Ex: HNO2 = Nitr-ite  ous + acid
Nitrous acid
H2SO3 =
Sulfurous acid

Naming Acids (cont.)
If the acid has two less oxygens than the base acid,
the naming goes as followed:
To Name:
Hypo + Polyatomic ion “ite”  “ous” + acid
Ex: HNO = Hypo + nitr-ite  ous + acid
Hyponitrous acid
HClO =
Hypochlorous acid

New Element On The Periodic Table
(cont.)
Physical Properties of Xx:
Generally round in form. Boils at nothing and may
freeze anytime. Melts whenever treated properly.
Very bitter if not used well.
Chemical Properties:
Very active. Possesses strong affinity to gold, silver,
platinum, and precious stones. Violent when left alone.
Able to absorb great amount of exotic food. Turns
slightly green when placed beside a better specimen.
Ages rapidly.

Writing Acids
Phosphoric acid
H3PO4
This is a Ternary acid (does not
begin with “hydro-”.
The “-ic” suffix indicates that the
polyatomic ion in this acid has a
suffix of “-ate” - phosphate
Assume that hydrogen is +1 and
balance the charges.

Hypochlorous acid This is a Ternary acid (does not
begin with “hydro-”.

H
ClO
The “-ous” suffix indicates that the
polyatomic ion in this acid has a
HClO
suffix of “-ite” - hypochlorite
Assume that hydrogen is +1 and
balance the charges.

Usage of Xx:
Highly ornamental. An extremely good catalyst for
disintegration of wealth. Probably the single most
powerful income reducing agent known.
Caution:
Highly explosive in inexperienced hands.
