Kinetics Experiments
Effect of concentration of HCl and NaOH on the rate of reaction with
Aluminum. |
|
|
|
Introduction:
Two well known chemical
reactions are the reaction of NaOH and HCl on aluminum.
Drano and
other solid drain cleaners usually consist of NaOH, and a small
amount of metallic aluminum. The aluminum reacts with NaOH to form hydrogen gas. The
formation of gas bubbles provides a
physical action that helps unclog a drain.
Anti-perspirants are made by the reaction of hydrochloric acid and
aluminum. |
 |
Since in this project you will learn
how to make antiperspirants, it is also good to know about the possible
health hazards of antiperspirants.
The human body has few areas from which
to purge toxins - behind the ears and knees, the groin area and armpits.
Toxins are eliminated in the form of perspiration.
As the name indicates antiperspirants
prevent perspiration, thereby inhibiting the discharge of toxins from
the armpits. Unable to sweat out these toxins, the body deposits them in
the lymph nodes below the arms, causing a high concentration of toxins
which leads to cell mutations - Cancer. Nearly all breast cancer tumors
occur in the upper outside quadrant of the breast area, precisely where
the lymph nodes are located.

Project
description:
In this project you will study the effect of concentration on the rate
of reaction of HCl and NaOH with aluminum. You will first come up with a
method of determining the rate of reaction. You will then perform
experiments to test the rate of reaction in different concentrations.
Report your results in the form of graphs or charts. |
