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. |
