# 6.3 Reading Table F and Table G ```UNIT 6 SOLUTIONS AND GASES
6.3 How do we read table F and G?
April 11, 2011
AIM: How do we know if a substance is soluble in
another, and to what extend?
DO NOW:
1. Define solubility.
How much of a solute will dissolve in a certain
amount of solvent
2. What factors affect solubility?
TEMPERATURE
PRESSURE
POLARITY OF SUBSTANCES
TABLE F
WORD
DEFINITION
SOLUBILITY
How much of a solute will dissolve
in a certain amount of solvent
SOLUBLE
Materials with high solubility
INSOLUBLE
Materials with low solubility
PRECIPITATE
Formation of a solid in a solution
CATEGORY
Dissolves or does
not dissolve?
SOLUBLE
Dissolves
INSOLUBLE
Dissolves
Formation of Precipitate?
No
Yes
Is NH4Cl soluble in H2O?
All ammonium ions are
soluble and halides (Cl-, Br-, I) are soluble.
Therefore, NH4Cl is soluble
in H2O.
Is silver chloride soluble in H2O?
All halides are soluble. However, the EXCEPTIONS are when
combined with Ag+, Pb2+, and Hg22+.
Since silver (Ag) is listed as an exception, silver chloride is insoluble.

TABLE G
WORD
SATURATED
“Just enough”
DEFINITION
a solution that contains a maximum
amount of solute that will dissolve
at a specific temperature
SUPERSATURATED
a solution holds more solute than is
present in a saturated solution at a
specific temperature
UNSATURATED
the solution holds less solute than
the maximum it can hold
“More than it can handle”
“Less than it can handle”
USING TABLE G
Table G tells us the grams of solute that can be
dissolved in H2O at various temperatures
