Get a pencil and paper and attempt to answer the questions
first . . . that is why its called review . . .
If you put a signed piece of paper in the top shelf of papers
to grade which says “MungaDinga Lunchbox” you will
receive extra credit on the exam

0.1 M C6H12O6
0.1 M C2H5OH
3. What happens to the conductivity
of a solution if KCl is added to a
saturated solution of KCl?
4. In a 0.01 M solution of HCl, blue
litmus will do what?
5. In the below reaction, which
quantity would be considered the
proton doner?


Pure water is similar to 1.0 M HCl in
that they both
Contain H3O+
 Are neutral to litmus
 Have a pH higher
than 7
 Are good conductors
of electricity

According to the Bronsted-Lowry
theory, an acid is any species that
can . . .
When tested, a solution turns red
litmus to blue. This indicates that
the solution contains two types of
ion. Which ion is more abundant?
What will water become if it acts as
a base?
+
H3O
12. In the reaction below is water an
acid, a base, or both?

H2O + H2O  H3O+ + OH-
BOTH

create a basic solution?




NaNO2
CaCl2
BaI2
MgSO4
What does this mean?
React each with water . .
If the product is a strong
base and a weak acid, it
will be a basic solution.
NaNO2 + H2O  NaOH + HNO2
