Copper Research Paper

The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle, copper was present in different forms. First reaction involves reaction between the copper and nitric acid, and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated. When solid CuO reacted with sulfuric acid, the copper returned to solution as an ion (Cu2+). The cycle of reactions was completed with the reaction where elemental copper was regenerated by Zn and Cu

During lab, we put the metal copper under different circumstances so that we could gain a better understanding as to what goes on in the copper cycle. Throughout each stage of the copper cycle, we deduced what type of chemical reaction took place based on observation, made observations about the state of the metal and what type of environment it was subjected to, and determined what the net ionic equation was for each stage. Following the experiment, we calculated what the percent yield was and compared the changes in mass from the initial stage to the final stage.

Copper is the 29th element in the periodic table, located more specifically at group 11, period 4. Because of its chemical and physical attributes, it is a transition metal, which denotes high boiling and melting points. Both a conductor of heat and electricity, Copper is ductile and malleable. Its symbol “Cu” derives from the Latin cuprum. Copper is also valued for its two-for-one practicality: it is a vital nutrient that has antibacterial properties. Aside from what many people generally know about Copper (the “common knowledge,” so to speak), there is much information regarding its atomic buildup.

PURE FOOD GRADE COPPER -- 100% pure copper, unlined, no stainless-steel and nickel-free for safe drinking; solid copper conducts thermal energy to keep drinks icy cold, even on hot days; same conduction keeps hot drinks warm and the handle cool-to-touch

     Copper is one of the earliest elements known to man. Because of its distinct red color, Copper is very easily identified. In the ancient times, copper could be found lying in the ground in its unattached state without interaction to other substances. Copper and its compounds have many uses in today’s society.

Copper is an element commonly found in Keweenaw Peninsula near Lake Superior in Michigan. To the facts Copper has twenty nine electrons and a melting Point of 1083.0 °C (1356.15 K, 1981.4 °F) there are twenty nine electrons in the copper atom why because it is the atomic weight or atomic mass.

Copper was the first metal used by man in 7000 BC. They used copper a lot in the bronze ages for swords. They use copper now in TV wirings, charges and mobile phones. Copper ore is mined both underground and on the surface. They dig large excavations formed called open-pit mines. There are about .5 oz. of copper in your mobile phone. That’s more than all the other metals in your phone and weighs 15% of your phone.

Being number 13 on the periodic table. Aluminum is a soft and not very strong metal. But when this metal is alloyed with other elements it increases it’ strength. Once it’s become stronger than it can be used in many useful means.

Copper has been in use by humans for tens of thousands of years. It is a pure substance that can be dated all the way back to the Roman Empire. Copper got its name from Cyprus of the Romans and was called Cyrium. It is extracted from ores by roasting the sulfate ore then leaching out the copper sulfate that was formed with water. Copper is known for its ductility and malleability. It is also one of the most electrically conductive metal elements. Copper is not as strong as steel so therefore it is very easy to bend. Copper is used for making wires and other useful materials.

As for metal, it has many uses. In fact, modern civilization has thrived off of things where iron is used like: buildings, car frames, bridges, and much more.

Copper is used for cords and is an essential element in plants and animals. Hans Christain Oersted discovered copper in 1825. Copper helped in many ways, all of our cords that we use everyday like chargers in the cords it has a strip of copper in it.

Copper is a ductile metal with high thermal and electrical conductivity. Ductility is a measure of how much pressure a metal can take before breaking apart. A metal with high malleability will be able to be drawn into long, thin wires without rupturing whereas a metal with low malleability will be brittle, although it may be strong, once it deforms enough, it will rupture. Most metals like Copper, gold, silver and aluminum are malleable because atoms can roll over each other and retain the structure of crystal, a function of metallic bonding. Copper is a pinkish color when it is new, but soon turns a reddish orange color after it is exposed to air, it is soft and bendy.

Iron is used all around us , the first thing that comes to mind with something I use on a daily basis is my cast iron cooking pots! It is also an important because it’s used in everyday life such as construction, our cars, and the train we used to get to work even our silverware.

For our science assessment we had the task to research about a metal of our choice. Since I am really into computers, I chose copper. A metal used in all kinds of wires, cpu’s and other stuff without a computer wouldn’t work. This fits really well into what we have to do for the second part, describe how this metal has helped human society.

into weapons or tools. Copper has been one of the most useful metals for over
