(Acids and Salts)
Bell RingerFriday, 12-3-10
Using your Periodic Table and your ion charts, name the ionic chemical
compounds:
NaClAlBr3HClH2SO4
AnnouncementsWe 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.

AcidsAn acid is a distinct type of compound.
Most acids used in the laboratory can
be classified as either:
binary acids
oxyacids
AcidsBinary acids are acids that consist of two
elements, usually hydrogen and one of the halogens - fluorine, chlorine, bromine, or
iodine.
HClHFHBrHI
AcidsOxyacids are acids that contain hydrogen,
oxygen, and a third element (usually a nonmetal).
HNO3 H2SO4
H3PO4
AcidsAcids 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 AcidsNaming binary acids:
Example: HFhydro + fluor + ic
Example: HClhydro + chlor + ic
Example: HBrhydro + brom + ic
Example: HIhydro + iod+ ic
Naming AcidsNaming oxyacids:Example: HNO3
nitr + ic Example: H2SO4
sulfur + icExample: H3PO4phosphor + ic
SaltsA 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.)
HCl NaOH+ - + -
Salts are named in the same way as other ionic compounds.
