Unit: Chemistry
Lesson 3: Describing Acids and
Bases
Essential Questions:
1.) What are the properties of acids?
2.) What are the properties of
bases?
Compounds with specific
properties
Acids
Bases
Properties of Acids
1.) Reactions with metals
A property that describes
a “wearing away” process
The purity of metals can be
determined by using acids.
Corrosive
2.) Reactions with Carbonates
 Acids react with carbonate ions to
produce a new salt, carbon dioxide and
water
Geologists use this
property of acids to
identify rocks made of
limestone.
3.) Sour Taste
4.) Reactions with indicators
A compound that
changes color when
it comes in contact
with an acid
Indicator
Properties of Bases
1.) Bitter Taste
2.) Slippery feel
3.) Reactions with Bases
 Bases do not react with metals or
carbonates
Chemical reaction in
which acids and bases
deactivate one another
Neutralization
4.) Reactions with indicators
