Copper sulphate

Introduction: Metallic copper and its compounds have played an important role in history, from ancient civilizations to today’s economy. It also has biological and environmental significance. In this experiment, we explored copper in its metallic and ionic forms and examined the reactions which form metallic copper and copper compounds as well as calculated percentage yield of final metallic copper product. Materials and Methods: In this experiment, 5 different chemical reactions took place before

Copper vs. Aluminum for household wiring 1 physical properties that make each substance well suited for household wiring: Copper Aluminum ductility: Copper is very ductile. The electrical industries benefit from the ductility of copper. malleability: fairly malleable and easy to work with. high thermal conductivity(high melting point): The thermal conductivity is very important because it allows copper wires, nickel coated or otherwise, to disperse heat. It also helps copper undergo extreme stress

fine light blue powder Chemical scoop full The powder begins to stick together and it turns a dark turquoise on the inside and a pale gray on the outside. When exposed to water, the solid dissolved, turning the water turquoise. A turquoise liquid (copper sulfate/water mixture) Iron/Sulfur #5 Iron filings- small gray granules, is drawn to magnet Sulfur – pale yellow powder, is not drawn to magnet 0.56g of each Iron is drawn to the magnet within the test tube, the sulfur does not. The sulfur settles

1 Extremely Basic Elements Why does the wire have to be copper? Because copper is a more electrically conductive material. The electrical conductivity of a material is a result of the movement of charged particles such as electrons. Matter (including copper) is made of charged particles such as leptons and quarks. Now, in the case of copper, because it is a more electrically conductive material, it has greater flow of free electrons (and vice versa). 2 This is the electric current flowing through

recovered copper was 5.22g, much greater than the initial mass of copper, 2.09. The number of moles of the recovered copper was calculated to be 0.0821mol while the number of moles of the initial copper was calculated to be 0.0329mol. The percent of copper recovered was calculated to be 250.%, and the percent error of copper recovered was calculated to be 150.%. From what seems to have been an increase in copper from the initial mass to the recovered mass, it can be assumed that the copper solid recovered

ZnSO4 dissolved into the water completely and the copper will be separated and in it’s solid form. This means the ZnSO4 solution will be clear and the copper will look brown. Group 5 has the best ratio according to color change, because the only group with those characteristics was Group 5. This is also because Group 5 didn’t have an excess materials from the reaction, meaning that the actual results should have been a clear ZnSO4 solution and brown copper. Group 1=0.08 moles of Zinc Group one didn’t

recover the copper metal using the copper cycle method and part B was to observed copper (I) compounds. Every copper complexes and compounds indicated in the experiment was observed very carefully. Any chemical changes in each step were recorded at instant. Such as, In Part B copper (II) nitrate was combined with sodium hydroxide to form an light blue precipitate of copper (II) hydroxide which upon heating, gives us a black colored precipitate of Copper (II) oxide. Moreover, obtained Copper (II) oxide

The history of chemistry has a span of time reaching from ancient history to the present. By 1000 BC. Ancient civilizations used a lot of different technologies that helped eventually form the different branches of chemistry. In my discussion about the history of chemistry, I will answer four questions that are very questionable. Such as, What was society like before the discovery of chemistry? How did natural resources limit or advance chemistry? How is chemistry affecting society today? And finally

essential such as zinc, copper, iron with respect to toxicity of certain metals like cadmium, arsenic, lead etc. It is assumed that the dietary intake of metals in excessive such as copper, iron and zinc will be protective against the toxic effects of the heavy metals like lead. The deficiency of calcium and other essential elements result in the enhanced toxicity of lead and cadmium [ref]. There had been difficulty in evaluating the role of essential nutrients like zinc, iron, copper etc on the toxicity
