Introduction

Investigate & comparing the industrial preparation of a pure metal with methods used in the laboratory Introduction Copper was discovered thousands of years ago in the Middle East and was first used as jewellery. Copper as one of the most important metals belongs to the transition and/or half precious metals. It is a relatively hard, at the same time very tough and flexible metal, which can be formed extraordinarily well into very thin lamellas and fine wires. Pure copper is red and thus beside gold the only coloured metal. With regards to its heat- and electrical conductivity it is situated between silver and gold. Copper can be alloyed very well, whereby it can be hardened considerably. The metal has a good chemical stability. Exposed to air it becomes only slowly covered with greenish patina (a mixture of basic sulphates, carbonates as well as chloride), which protects it against further corrosion. About half of the copper production is used in electro-technology, where it is used as conductor in cables, generators, transformers or engines. About 30% of the production are processed into alloys. Important ores of copper Copper pyrite or chalcopyrite (CuFeS2). ...read more.

Middle

For comparing the laboratory and industrial process of getting pure copper, I will do the following things: � I am going to research on how the industry produce pure metal and what equipment they use � I will look at the differences and similarities between the lab and industry � Also I will look at the cost at which industry and laboratory produce metal with I will identify that why we used different equipment in the laboratory then in industry, finally I will say about the effect of economic and environmental factors, which affect the production of copper and then will write an evaluation. The laboratory process Apparatus Beaker Balance Spatula Carbon Rod Measuring cylinder Ammeter 2 crocodile clips Sulphuric acid Wire Power supply Pieces of cardboard Method I will weigh 2g of malachite into a beaker. Then I will measure 50 of sulphuric acid and add it slowly to the malachite. I will weigh the carbon electrodes. These will be placed in the solution of copper sulphate in the beaker and connected to an electrical circuit in the experiment, which was connected to the power supply. I will set the power supply to 2 volts and pass the current through the solution for 20 min. ...read more.

Conclusion

In laboratory its not risky as industry but still experiment we do can damage our health We didn't use recycling in the Industry use recycling to recycle lots of materials It reduces the financial costs of the industry Evaluation I faced some difficulties in the beginning of the assessment because the information that was required to compare the industrial process with laboratory process was hard to find. At first I tried a lot to have a contact with the company, which produce copper but then I didn't had any reply from them. Then I searched on the Internet and found how they extract copper in the industry. The things that I learned from this assignment: � The way the industry extract copper � The difference between the laboratory process and industrial process � The factors that affect the copper production in industry � The effects copper production on environment. My weakness in this assignment was that I couldn't find the information at the beginning and wasted some time on it. My strength in this assignment was that I could compare the industrial and laboratory process well. I could improve my work by looking at more resources other and not waste a lot of time on researching. ...read more.

  1. Thermal Decomposition Of Metal Carbonates

    Having done this you can then place a glowing splint inside the test tube. A pop sound can be heard if hydrogen is present in the test tube. The reactivity series was determined by how all of the metals react to the air, water and dilute acid.

    solution, and this may have slightly affected the forming of copper atoms at the cathode. And finally another inaccuracy is that on one occasion, the crocodile clip holder slid into the solution, so the crocodile clip was exposed to the electrolyte.

  1. Electrolysis of Copper Chloride

    The electrodes were connected to crocodile clips, and the clips to the power pack. Extra care was taken to keep the electrodes away from each other, so that it does not intercept with the reaction. A steady voltage flowed and the experiments ran for a period of 5 minutes.

    Plastic bags don't just kill animals they can also kill humans, as some young babies and children could suffocate on them, in other cases if a parent doesn't want their child they can suffocate the baby themselves and kill them.

    the electrolyte by the anode as more electrons are being taken away from it. Similarly, if the electric current is smaller, fewer electrons are being supplied to the cathode and fewer taken from the anode. Michael Faraday was one of the first scientists to study electrolysis.

  2. Thermal Decomposition of Metal carbonates

    The formula for how a metal reacts with dilute acid is: Metal + Acid = Metal Salt + Hydrogen The hydrogen that is given off in the above reactions can be indentified by capturing the hydrogen in a test tube.
