Using your Periodic Table and your ion charts,
name the ionic chemical compounds:
NaCl
AlBr3
HCl
H2SO4
Announcements
We will have a test next
Tuesday.
The remediation for
TEKSCheck #2 is now
available, but you must come to
me to get clearance to take it.

Acids
An acid is a distinct
type of compound.
Most acids used in
the laboratory can
be classified as
either:
binary acids
oxyacids
Acids
Binary acids are acids that consist of two
elements, usually hydrogen and one of the
halogens - fluorine, chlorine, bromine, or
iodine.
Acids
Oxyacids are acids that contain hydrogen,
oxygen, and a third element (usually a
nonmetal).
Acids
Acids were first recognized as
a specific class of compounds
based on their properties in
solutions of water.
Consequently, in chemical
nomenclature, the term acid
usually refers to a solution in
water of one of these special
compounds rather than to the
compound itself.
For example, hydrochloric acid
refers to a water solution of
the molecular compound
hydrogen chloride, HCl.
Acids
Naming Acids
Naming binary acids:
Example: HF
hydro + fluor + ic
Example: HCl
hydro + chlor + ic
Example: HBr
hydro + brom + ic
Example: HI
hydro + iod+ ic
Naming Acids
Naming oxyacids:
Example: HNO3
nitr + ic
Example: H2SO4
sulfur + ic
Example: H3PO4
phosphor + ic
Salts
A salt is an ionic
compound composed of
a cation from a base and
the anion from an acid.
For example, table salt
(NaCl) contains the
anion from
hydrochloric acid (HCl)
and the cation from the
base sodium hydroxide
(NaOH.)

Salts are named in the
same way as other
ionic compounds.
