Study Sheet: Identification of Strong and Weak Acids
you are asked to identify a substance as either (1) an Arrhenius strong acid,
(2) an Arrhenius weak acid, (3) an Arrhenius strong base, (4) an Arrhenius weak
base, or (5) not acidic or basic in the Arrhenius sense (neutral), you can use
the following procedure.
Identify the substance as an acid, a base, or neither.
The names of the uncharged acids end in acid.
The names for the only ionic compounds
you are expected to recognize as acidic end in hydrogen sulfate or
Molecular acids have one of these forms: HX(aq) or HaXbOc.
Acidic ionic compounds have formulas that include HSO4-
Base Names and Formulas:
We expect ionic compounds that contain
group 1 or 2 metal cations to be basic except those containing:
Cl-, Br-, I-, NO3-,
Ammonia, NH3, is a base.
If you have
an acid or base, determine whether it is strong or weak.
We will consider all acids except HCl(aq), HBr(aq), HI(aq),
HNO3, HClO4, and H2SO4 to be weak.
We will consider all bases except metal hydroxides to
