Recycling Aluminium Research Paper

735 Words3 Pages

INTRODUCTION
The metal that can be recycled over and over again and in turn saves energy and natural resources – Aluminium, is silver and soft metal which belongs to the 13th group and is a part of p – block elements.
It was first isolated by Friedrich Wohler in 1827 and then named by Humphry Davy in 1807.
The atomic number of Aluminium is 13 and it has electronic configuration – [Ne] 3s² 3p¹.
HISTORY
Aluminium salts was used by Greeks for dyeing and dressing wounds in ancient times. Later on, Hans Christian Orsted produced an impure form of Aluminium in the year 1825. Further, Pierre Berthier discovered the metal Aluminium in bauxite ore.
FACT : In the late 19th century aluminium became more valuable than gold.
Hall – Helroult electrolytic …show more content…

FACT : On replacing a few Aluminium ions by chromium ions in Aluminium oxide, ruby gemstones can be obtained.
RECYCLING
Theoritically, Aluminium is said to be 100%recyclable without losing its natural qualities. Until 1960s, recycling was a low profile activity but the growing use of Aluminium cans has now seen the setup of aluminum recycling industries.
Recycling aluminium includes simple steps from melting the scrap (requires really less energy) to extracting aluminium.
The secondary aluminium that is obtained after recycling is said to maintain the same physical properties as primary aluminium.
FACT : Recycling one aluminium can saves enough energy that can be used to run the television for 3 hours.
HEALTH CONCERNS
Aluminium, till date, is seen to have no known function in biology. Aluminium salts are observed to be non – toxic or can also be said to have very low toxicity.
Acute toxicity is traced when it deposits on bone and central nervous system which in turn reduces the renal function of the patient. High dosage of aluminium leads to neurotoxicity and osteopenia.
Aluminium has controversially been stated to be one of the factors in Alzheimer’s

  • Wasteland Reaction Paper

    Wasteland is a documentary by Lucy Walker that depicts the lives of selected garbage pickers in Jardim Gramacho – a massive dumpsite found in the outskirts of Rio de Janeiro. The film is about Vik Muniz’s 2-year journey back to his home country seeking to give back to an impoverished community through making images out of an unusual material – trash. The film featured 7 garbage pickers from the landfill, and each has a story that brought them to their current places. One unique thing about the whole creative process is that the pickers themselves became part of it. Vik imagined that as they work on their own and each other’s images, the pickers will not only show themselves to a broader world that is for now comfortably oblivious of their existence, but also see themselves differently (Fuchs, 2010).

  • Empirical Formula Of Copper Chloride Lab Report

    729 Words  | 3 Pages

    As soon as the wire was submerged into the solution, the aluminum atoms and the copper (II) ions underwent a reduction-oxidation (redox) reaction, meaning aluminum was oxidized and donated its electrons to the copper ions, which were reduced. As a result, solid copper began to form on the surface of the aluminum wire, giving the wire a brown-orange color that resembled rust. The wire had to be regularly shaken in order to remove the solid copper particles and thereby expose more of the aluminum wire to react with the surrounding solution. As the reaction progressed, the liquid copper chloride solution slowly began to lose its color and turn clear. This was a chemical reaction, as seen by the bubbles formed with the wire was added, meaning gas was released when aluminum was oxidized and copper was reduced, but it also gave rise to physical changes, such as the change in color of the solution from blue-green to rusty orange to clear.
