Synthesis And Analysis Of Copper Lab Report
Objective: The objective of this lab is to determine and analyze the many chemical qualities of copper , by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper, Concentrated HNO3, 6 M NaOH , Bunsen burner, 6 M H2SO4, Mg ribbon, and two test tubes. The techniques used in this lab which is cleaning glassware, disposing of chemicals , measuring mass , centrifugation , venting gases, and test tube over a “cool” flame. Introduction: Copper is an amazing metal that exists in almost everything that uses electricity as a power source or as a mean of charging batteries , this is because copper is a very good conductor of electricity. Copper is known as an

alloying agent , is an element that can be combined with other elements in order to produce metals with unique properties ; we use copper as an alloy since it has a very rigid tensile strength , it may not be a tough physical properties but it does not break very easily causing it to be alloyed with varies metals like brass , bronze , and steel.
Oxidization of the surface of copper that produces a blue-green layer is called patina. The cleaning of glassware was done in the end of the experiment to avoid cross contamination . The disposing of chemicals was done throughout most of experiment with inputing concentrated HNO3, 6 M NaOH , and 6 M H2SO4 ; extreme caution was used during the insertion of chemicals into the solution , since these chemicals are extremely corrosive and can evaporate skin ; the disposing of chemicals were also done at the end of the experiment into the waste container to avoid harsh chemicals into the water supply and plumbing. In addition, to using safety when pouring chemicals , safety was also used when gases were being vented in the fume hood. In part a , NHO3 is very toxic to inhale so the use of the fume hood is needed. In part e,
the gases dispersed from the Mg strips are toxic and must be done in the fume hood. The mass was then measured using a scale in the beginning the experiment with the copper inside a test tube , and in the end with finding the final mass of the copper. Centrifugation was used in part B to separate the the Cu(OH)2 and the solution ,and part e where you would separate the Cu(s) from the solution. Lastly, the use of a “cool flame” in part c was done in order to cause the chemical reaction of copper hydroxide to copper oxide. Conclusion: In conclusion , my numbers are not reasonable since my percent recovery is high compared to when we started , the final result was 2,178 percent of copper than what we started with. This was caused by not evaporating the water on Part C.
