Health Effects Of Copper Essay

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

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.

To complete the research a scientist went out to the Delaware River three different times at 6 different locations (Shi, Allen & Grassi, 1998). He collected the water and brought it back to the lab to be tested (Shi et al., 1998). The research method that was used was sampling and collecting data to see if the river has a high rate of copper in it (Shi et al., 1998). The results of the journal were also conclusive. Data was shown that when the water went through treatment plants or through sewers the water would come out with more copper than without going through these places (Shi et al., 1998). In the long run, the water is safe depending on where and when you collect the water for use (Shi et al.,

Copper is a naturally occurring element that can be found in all plants and animals. A certain amount of copper is necessary for health, and the human body has developed a way to maintain the proper level of copper in it (Minnesota). Even so, large concentrations of copper, and general long-term exposure, can have a negative impact on the body. Symptoms include stomachaches, vomiting, diarrhea, liver and kidney damage, and even death (Lenntech). Exposure to copper comes from many areas, but the most common one is through the water. Copper is commonly found in plumbing pipes, which can lead to high levels of copper in drinking water and fresh water sources due to erosion. Lakes and streams are also treated with copper to prevent algae overgrowth (Group).

Did you know the Statue of Liberty is made of copper? The Statue of Liberty is not originally green, it was a dull brown colour but turned green from many years of oxidation.Copper (Cu), Copper’s atomic number is 29 and has the atomic weight of 63.546.Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal, electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA.Copper has the melting point of 1,981° F (1,083° C) and a boiling

Copper has been promoted as a bone disease preventative as horses use copper in bone, cartilage, and pigment formation.

The Copper Cycle is a popular experiment used to determine if an element, in this instance, copper, reverts to its elemental form after a chain of reactions. This experiment is very dangerous because of the reactions between the strong acids and bases. In this experiment I performed a series of reactions starting with copper metal and nitric acid to form copper (II) nitrate. Then I reacted copper and several other solutions such as, sodium hydroxide, sulfuric acid, ammonium hydroxide, and hydrochloric acid to form precipitates. In conclusion my percent recovery

Copper commonly occurs as a pollutant in surface fresh waters and it can be extremely toxic to fish , and so its removal is often necessary . There are several methods that exist in the actuality, such as adsorption on activated

The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate, CuSO4, mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was found to be 2.1726g which meant that through limiting reagent analysis Fe was determined to be the limiting reagent and the chemical reaction was determined to be as following:-

While copper is potentially toxic to humans when ingested in excess amounts, copper toxicity (Copperiedus) is very unlikely. The most common cause of copperiedus is eating acid foods cooked in uncoated copper pans or cookware, or from excess copper in drinking water. Copper does not react with acids or bases unless either is a strong oxidizing agent. Due to the fact that the oxygen molecule in water is locked into a compound with one oxygen atom and two hydrogen atoms.

Copper is a key mineral in many different body systems. It is central to building strong tissue, maintaining blood volume, and producing energy in your cells. Yet, for all its critical importance, you don't have much copper in your body. In the foods we commonly eat, there are only very small amounts of copper. As much as any dietary mineral, the amount of copper you eat is directly related to the amounts of minimally processed plant foods you get every day. Copper is required to manufacture collagen, a major structural protein in the body. When copper deficiency becomes severe, tissue integrity—particularly bones and blood vessels—can begin to break down. The DRI report also established a Tolerable Upper Intake Level (UL) of 10 mg per day

The source of copper is from mining, metal piping, and chemical industry. Copper attaches to the organic matter once it is released into the soil. Humans may be exposed to copper through the intake of contaminated food, and drinking water. Copper causes liver and kidney damage, anemia and stomach and intestinal

Copper does not rust and when in water, it turns reddish orange. After prolonged exposure, Copper develops a coat of green film called patina. This film protects it against further exposure. Also, rolled Copper has a tensile strength from 50,000 to 70,000 pounds per square inch. Tensile strength is the maximum strength a material can stand before breaking.

When the zinc was added to the copper (II) sulfate solution, the solution started to bubble. As the solution was stirred, it turned a cloudy blue. Small flecks of a brown solid were visible. As the solution became colorless, the brown solid settled to the bottom of the beaker. The solid formed was copper in its elemental state. The color faded from the solution as the copper ions slowly formed into solid copper. The copper was poured into a funnel with filter paper and washed three times with 25 mL
