Redox Project
Name: ______________________________________
Date: _____________
Your Task:
Select
2
applications of redox reactions from the list
below and create a 1 page
flyer
(on a
n
8.5” x 11” piece of paper)
explaining the process
es
, including the f
ollowing information:
o
An explanation of why
each
reaction is useful
o
The complete, balanced chemical equation
s
o
Half reactions, labeled to show which element
s
are
being reduced, and which
are
oxidized
o
A picture illustrating each reaction’s use or its end
-
pr
oduct
The paper should be divided in half, with each reaction explained separately.
A good reference is
chapter
s
20
and 21
in your textbook
.
Some Real
-
Life Examples of Redox Reactions in Action
:

The combustion of
natural gas
(methane
, CH
4
)

A sequenc
e of redox reactions are used to burn sugars, such as
glucose
(C
6
H
12
O
6
),
in our
bodies
.

Explosives
often contain oxidizing and reducing agents in the same com
pound, such as
nitroglycerine
. When activated, a highly exothermic redox reaction occurs in which
large
amounts of gasses are formed, which expand and create a shock wave.

The processes involved in developing
photographic film
can be initiated by a single light
photon, which activates
the decomposition of a
grain of silver bromide in the film.

Blea
ches
are oxidizing agents. Color is caused by the movement of electrons between
different energy levels, and it can often be eliminated by removing these electrons through
oxidation.

Hydrogen peroxide
fizzes
when poured on a cut because the H
2
O
2
is being
decomposed
. In
doing so, it kills bacteria by literally oxidizing them to death.

In
photosynthesis
,
chlorophyll molecules use light energy to
decompose
water into oxygen
gas.

A
“
Breathalyzer
”
test measures the alcohol content in your breath by means of a
redox
reaction.
A
color
change
indicates the amount of alcohol in your body.
