BaileyAcknowledgementsMy mom helped me alot in this experience and guided me through picking out the metals and the entire experiment itself. How fast? BaileyPurpose & hypothesis During the summer, I became more informed of the easily contracted disease known as Tetanus. Tetanus is a potentially fatal disease caught by contact with contaminated surfaces or objects. The most effective object that causes Tetanus known to man is rusted metal. The purpose of this experiment is to test four of the most used metals’ rusting speed and from that determining which metal rusts the slowest and the fastest. Using a metal that is slow to rusting in everyday life can decrease the Tetanus rate by a fair amount. The metals I will be using will be brass, Iron, steel, and Aluminum. My hypothesis is that Iron will be the first metal to begin rusting. Based off of research, aluminum oxide and chromium oxide act as protective coatings, as if corrosion serves as a form of protection. However, rusting on Iron does not protect it from further corrosion. If I expose Iron, Brass, Steel, and Aluminum to the same rusting agents, then, Iron is most likely to rust the quickest because it is more porous than other metals, leaving it vulnerable to further corrosion. How fast? BaileyBackground research Although it looks simple and quite unsanitary, rusting and corroding has a lot of science behind it. Rusting is the aftermath of a chemical reaction between atoms and electrons. The conductivity of moisture around metals is caused by Salt and acids. Metals deteriorate quicker under moist and damp environments. Other chemicals increase the activity of electrons between iron and oxygen. Another word for the chemical bonds of rusting is Iron oxide or Fe2O3. In fact, Iron is the most common rusting metal. Iron is in the metals category of the periodic table and has an Atomic number of 26. Its melting point is 2800 degrees fahrenheit and it is 5.6% of earth’s crust. Archaeological evidence proves that people have been using iron for centuries in trades, weapons, architecture etc. Iron is also one of the many magnetic metals. Iron is in your blood and is a mineral from the protein Hemoglobin.There are over 35000 different grades of steel that exist on earth. Various elements bond to produce it. Depending on the alloy, commercial steel is divided into four separate groups. Carbon, alloy, stainless, and tool steels give it a wide range of mechanical uses. It is most commonly used in the construction of railways, roads, buildings and other set ups and it’s boiling temperature is 1510 degrees fahrenheit.After steel is the second most used metal, Aluminum. Aluminum’s boiling point goes up to 1220 degrees fahrenheit and its atomic number is 13. Aluminum is known for it’s flexibility and durability. Aluminum is the second most used metal due to its quality and efficiency. Unlike steel and iron, it is non magnetic. Mostly used for window frames, kegs, cans, utensils and other minor devices. Brass is more commonly used for instruments, locks and casings. Brass is primarily produced from copper and zinc.Materials and ProcedureFor my procedure I tested four different metals under four different rusting agents. For the rusting agents I used bleach, water, salt, and baking soda.The tested metals were Brass, Steel, Aluminum and Iron. For my metals. I possessed small tubes of each one. With a Wire cutter I cut the tubes into four five inches pieces to fit into petri dishes in which i will expose the metals to the four rusting agents. After conducting the experiment. I wait many days to determine the fastest rusting metal and the fastest rusting agent. I will measure the amount of the tube the rust covered using centimeters compare the metals’ results. How fast? Bailey Results How fast? BaileyConclusion, Reflection, ApplicationAfter this experiment I would say that I could’ve picked a better list of tested metals. For Iron is partially made of steel. That probably affected my experiment and results when it came to Iron’s rusting speed. As for steel, many other element from the periodic table produce it. Baking soda and salt were mixed with water rather than them interacting with the metals alone. When it comes to the real world. Picking a metal that is lowest to rust can solve many problems including the rate of tetanus decreasing. Magnetic metals like iron and steel can be used to make innovative forms of transportation Maglev bikes, trains, and cars. It can also save a lot of money worldwide.Reference list”What Chemicals Rust Metal Rapidly?” What Chemicals Rust Metal Rapidly? | Education – Seattle PI, education.seattlepi.com/chemicals-rust-metal-rapidly-4952.html.Metals, Online. “Aluminum.” Aluminum – Online Metal Store, www.onlinemetals.com/merchant.cfm?id=60&step=2.”Aluminium – Element Information, Properties and Uses | Periodic Table.” Royal Society of Chemistry – Advancing Excellence in the Chemical Sciences, www.rsc.org/periodic-table/element/13/aluminiumBell, Terence. “All About Steel.” The Balance, 2 Mar. 2017, www.thebalance.com/metal-profile-steel-2340175.”About Steel.” About Steel, www.worldsteel.org/media-centre/about-steel.htmlGagnon, Steve. “It’s Elemental.” It’s Elemental – The Element Iron, education.jlab.org/itselemental/ele026.htm”IRON: Uses, Side Effects, Interactions and Warnings.” WebMD, WebMD, www.webmd.com/vitamins-supplements/ingredientmono-912-iron.aspx.The Editors of Encyclopædia Britannica. “Brass.” Encyclopædia Britannica, Encyclopædia Britannica, Inc., 2 Dec. 2013, www.britannica.com/technology/brass-alloy.”Why Do Some Things Rust?” Wonderopolis, wonderopolis.org/wonder/why-do-some-things-rust.Helmenstine, Ph.D. Anne Marie. “How Brass Compares to Bronze.” ThoughtCo, www.thoughtco.com/brass-composition-and-properties-603729.
