Kinetics
The basic idea of any project is to learn something and have fun doing it.
The best way to learn and retain something is to do it yourself. This idea
makes science projects so important and popular. You will learn something
much better by experimentation and trials.
Reaction experiments are very important because almost every chemical reacts
differently with something. For example, sodium reacts very violently with
water. Acids react and can cause burns with other substances. Even
your household cleaning solutions can produce some dangerous reactions.
Therefore, it is important to be careful when producing these experiments.
Developers at scienceproject.com created the following experiment that has
practical and educational value.
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 you results in the form of
graphs or charts.
