 Taste sour
 Change the color of an acid/base indicator
 Conduct electricity when dissolved in water


Arrhenius Acids and Bases

Arrhenius acids Always begin with H
 Ionize to form H+ in aqueous solution

Arrhenius bases Always contain OH- (hydroxide)
 Produce hydroxide ions in solution

This is the most specific and exclusive
definition of acids and bases

Naming Acids
When the name of the anion paired with H+ ends in
–ide, the acid name begins with hydro-. The stem
of the anion has the suffix –ic and is folllowed by
acid.
2. When the anion name ends in –ite, the acid name is
the stem of the anion with the suffix –ous, followed
by acid.
3. When the anion name ends in –ate, the acid name
is the stem of the anion with the suffix –ic, followed
by acid.

carbonic acid
H3PO3
nitrous acid
HNO3
acetic acid
H2SO4

Naming Bases

Bases are ionic compounds, and are
named just as all other ionic compounds
are.
KOH
Fe(OH)3
Ca(OH)2
sodium hydroxide
magnesium hydroxide
