2. Acids Arrhenius acids produce H+ ions in water. H2O
HCl(g) H+(aq) + Cl- (aq)
are electrolytes.
have a sour taste.
turn litmus paper red.
neutralize bases.

3. Names of Acids
Acids with H and a nonmetal are named with the prefix hydro and end with ic acid.
HCl hydrochloric acid
Acids with H and a polyatomic ion are named by changing the end of the name of the polyatomic ion from ate to ic acid or ite to ous acid.
ClO3− chlorate HClO3 chloric acid
ClO2− chlorite HClO2 chlorous acid

4. Names of Some Common Acids

5. Learning Check
Select the correct name for each of the following acids. A. HBr 1. bromic acid 2. bromous acid 3. hydrobromic acid B. H2CO3 1. carbonic acid 2. hydrocarbonic acid 3. carbonous acid C. HBrO2 1. bromic acid 2. hydrobromous acid 3. bromous acid

6. Solution
A. HBr 3. hydrobromic acid
The name of an acid with H and one nonmetal uses the prefix hydro and ends with ic acid.
B. H2CO3 1. carbonic acid
An acid with H and a polyatomic ion is named by changing the end of an ate ion to ic acid.
C. HBrO2 3. bromous acid
This acid of bromite (BrO2-) is bromous acid.

7. Bases Arrhenius bases produce OH− ions in water.
taste bitter or chalky.
are electrolytes.
turn litmus paper blue.
feel soapy and slippery.
neutralize acids.

8. Some Common Bases
