Question:

 

Will certain household items prevent rusting?

 

 

Hypothesis:

 

My hypothesis is that the following materials will prevent the process of rusting. The materials are dish washing liquid, Vaseline, and paint (Rustolium.)

 

I think Vaseline will prevent rusting the most, then paint, and finally dish washing liquid.

 

 

 

 

 

Background

 

Iron is a silvery white solid metal. It appears in-group VII of the

 

periodic table as a transition element. Its atomic number is 26, and its

 

atomic weight is 55.847. Its chemical symbol, Fe, is retrieved from ferrum,

 

the Latin word for iron. In its various compounds, iron is the fourth most

 

abundant element in the Earth's crust. Iron is soft and malleable and ductile

 

at room temperature. It melts at 1,535 degrees Celsius and boils at 3,000

 

degrees Celsius. Pure iron can exist in two structural types, or allotropic

 

forms. They are a-form and gamma-form.

 

Corrosion is the natural deterioration or destruction of a material as a

 

result of its interaction with the environment. The term is applied mostly to

 

metals and particularly to their reaction with oxygen, or rusting. The cost of

 

replacing corroded equipment and protecting existing structures exceeds $10

 

billion dollars each year in the United States. Corrosion of metals is

 

generally confined to the surface. The most common means of thwarting

 

corrosion is to apply a resistant surface coating or lining. Paint, plastic,

 

rubber, and ceramics are commonly used, and metals are often plated with a

 

more resistant metal such as nickel or chromium. Iron is easily oxidized and

it reacts directly with most common nonmetallic elements. The most

 

important chemical reaction of iron is corrosion. When corrosion occurs,

 

water and oxygen interacts with iron and creates iron oxide or rust. The

 

corrosion of iron has been studied very carefully. The formation of rust is

 

known to be a electrochemical reaction. In order for rust to form at room

 

temperature , three compounds in addition to iron must be present: oxygen,

 

water, and electrolyte. Iron that is partially immersed in salt or freshwater

 

usually rusts more quickly than does iron that is totally immersed.

 

Formation of rust begins when the relative humanity exceeds 50%. The

 

presence of air pollutants, particularly the oxides of sulfur, increases the

 

the rate in which rust forms. The formation of rust may be inhibited by

 

using a certain oxide protective coating.

 

Mineral, a household item, is a clear, colorless liquid, without order

 

or taste, that is used medicinally as a lubricant and laxative, as an oil base in

 

cosmetics, and as an ingredient of paints and varnishes. It is also called

 

liquid petrolatum or petroleum jelly, used in ointments and dressings.

 

Another household item that I used in my project was paint. The

 

chemicals in this rust resistant paint were toluene and xylene.

 

They are petrochemicals produced from natural gas liquids, or refinery

 

products derived from crude oil distillation, or cracking. First stage

 

petrochemicals, including ethylene, propylene, butylenes, benzene,

 

toluene, and xylenes are produced as a starting point for a number of

 

secondary petrochemicals that are transformed into a variety of

 

petrochemicals and products. These are some of the products: Plastics,

 

Solvent, Synthetic Fibers, Elastormers, and other essential commodities.

 

Some of the products referred to as petrochemical were in the past

 

produced from charcoal, coal-tar distillation by products, Acetylene, or

 

fermentation alcohol. The growth of refining industry is the United States,

 

based on abundant petroleum and natural gas resources as well as on the

 

development of advanced thermal and catalytic oil-cracking processes,

 

created the conditions for the present petrochemical industry.

 

Oxygen is the most abundant element on Earth. Oxygen is practically

 

in everything form animals to plants to humans. Oxygen is also found in

 

minerals such as diamonds and gems, rocks, and a lot of other things. The

 

atomic number of oxygen is 2 its atomic mass number is 15.9994.

 

Oxygen's chemical symbol is O.

 

 

Glossary of Terms

 

  1. Corrosion-to eat into or wear away slowly, as by the action of acid and rust.
  2.  

  3. Oxidation-the act of oxidating or the condition of being oxidized.
  4.  

  5. Transition element-a element that is neither a metal or non-metal, but has characteristics of both.
  6.  

  7. Malleable- means it can be pounded into a sheet.
  8.  

  9. Ductile-means that it can be put into a wire.
  10.  

  11. Iron Oxide- means rust.
  12.  

  13. Electrolyte-any dissolved compound that can carry an electric current and can be broken up into its parts by the current.

Experimental Procedure

 

  1. Gather all of the material: Vaseline, paint, dish washing liquid, three nails, and three cups of clean water.
  2.  

  3. Carefully situate each cup on a flat surface.
  4.  

  5. Place an iron nail in each of the cups.
  6.  

  7. Coat each nail with the Vaseline, paint, and dish washing liquid with a Q-tip.
  8.  

  9. Fill each cup with water just a little more than half way.
  10.  

  11. Place the coated nails into the water.
  12.  

  13. Let the nails sit there for about six weeks.
  14.  

  15. Record observations and Results every day for the six weeks

Conclusion

 

My conclusion is that the Vaseline is the technology that prevented

 

the rusting the most, then the paint, and finally the dish washing liquid. The

 

reason why I think the Vaseline corroded the least of all the substances, is

 

because of its thick coating made of mineral oil. Mineral oil is also used in

 

car's engines to prevent rusting in the engine. It is used in a form called oil.

 

Usually people don't coat things with Vaseline naturally, but the mineral oil

 

inside of the Vaseline is what makes it important.
