Copper sulphate

Chemplate Magnesium Goggles Copper Toothpicks CuSO4 (Copper (II) Sulfate) AgNO3 (Silver Nitrate) HCl (Hydrochloric acid) Procedure: Take a chemplate and put one or two pieces of zinc, copper and magnesium as shown in the figure. Then add 5 to 10 drops of given solutions into each well. Observe the reactions for 10 minutes and record. Data/Observations: Reaction 1 Zn + CuSO4 → ZnSo4 + Cu Hypothesis: There is going to be a reaction because zinc is more active than copper Your Finding: Color change

have we learned about the mining for copper that could minimise environment impacts of mining in the future?” Copper is a metal used for jewellery, copper wiring, electrical motors, engines, but mainly used in electrical generators and powers. This is because copper has a high thermal and electrical conductivity. Hence, copper is essential in today’s society. The mining for copper in Queenstown, Tasmania was founded in 1883, but first started in 1896. Copper mining led to the formation of acid

Some lab techniques learned in this lab are decanting, using a pistol grip when transferring beakers to one place to another and during decanting, and using a piece of partially submerged aluminum wire in the copper sample, shaking the wire around, and dislodging any particle of copper precipitate forming on the aluminum wire. Decanting is a lab method used to separate mixtures of solutions and solids by allowing the solid to rest at the bottom of the solution and slowly pouring the liquid out of

dependent on CuO. Also the X-ray photo electron spectroscopy results showed that the iron ions were in the ferric state for all glass samples containing Fe2O3 mol% more than 7.5. The electrical and absorption properties depend on the oxidation state of copper and the effect of mixed transition metal.

conclusion, the charge/roman numeral on copper in copper sulfate is 2+. The percent composition of copper in copper (I) sulfate was 40.58% and in copper (II) sulfate it was 25.46%. Later, I calculated that the percent of copper in the lab was 26.13%. This percent shows that copper (II) sulfate was used in this experiment because 26.13% was closer to 25.46% than 40.58%. If iron (II) sulfate and copper metal is the product of copper (?) sulfate and iron metal, then copper (?) sulfate has a charge of 2+. The

between copper sulfate and an iron nail. This experiment is significant because it is a test of what I will do with a francium and water reaction. The reaction between copper sulfate and iron is a single displacement reaction where the iron eventually replaces the copper and creates iron sulfate. Iron is able to displace copper in this reaction because it is more active. In the reaction iron can either solid or aqueous but copper sulfate must be aqueous to facilitate the reaction.

1. Explain why the iceman was so well preserved? ( source one) It is said that a frozen body will stay preserved over hundreds, even thousand of years. During the first stage of investigations Austrian archaeologist Konrad Spindler researched the layout which had proved that the iceman’s body position and placement of weapons were preserved in the same position from when the Iceman had died, it had also been proved that the body was initially covered in a thin layer of snow which had helped complete

3rd, 2009 Lab Report #3: Copper Cycle Abstract: 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

reaction or next step. In this experiment, copper was changed through eight different reactions. Throughout the process, qualitative observations were recorded to see what effect each type of acid and decanting has on copper. All of these steps were successfully completed by using different acidic solutions and zinc to take copper through the cycle from copper solid to copper nitrate to copper hydroxide, to copper oxide, to copper II sulfate, and back to copper solid. Procedure: CHE 131 Experiment 8

this, and why hasn’t the EPA forced action? The deadly Berkley pit Butte, Montana, once known as “The Richest Hill on Earth,” has a long history in copper mining. But, a century of mining has left scars, and a huge toxic pit smack dab in the center. The Berkeley Pit, a former open-pit, copper mine opened in 1955 and was operated by Anaconda Copper. It was later operated by the Atlantic Richfield Company. When it closed in 1982, the water pumps in the nearby Kelley Mine — 3,800 feet below the surface
