Dr. Jefferson Andrews Chemical Principalities - CHEM 1101 1 October 2008 Copper, the Funnest laboratory Ever. Abstract: This taste served as a test of our individual(a) laboratory skills in carrying egress out some(a)(prenominal) Abstract: chemical substance transformations involving slob. The experiment was successful in that the Abstract: percent turn over was reasonable, and we were able to reanimate our betrayer sample with Abstract: supreme efficiency ( we were able to call back all of the hair with which we began ). entry: This experiment involved the detachment and purification of our desired crossroad ( copper ) from any chuck out side products. This was accomplished apply several(prenominal) different methods including filtration, sedimentation, decantation, extraction, and sublimation. In addition to carrying out some of these operations, we familiarized ourselves with both oxidation-reduction and metathesis reactions, two primitive types of chemical reactions. Through these reactions, we performed several chemical transformations involving copper, and were able to incur our copper sample with utmost efficiency, thus accomplishing the objective of the experimentto recover all of the copper with which we began.
We performed the following chemical reactions: Cu ( s ) + 4 HNO3 ( aq ) → Cu( NO3 )2 ( aq ) + 2 NO2 ( g ) + 2 piss ( l )oxidation-reduction [ i ] Cu( NO3 )2 ( aq ) + 2 NaOH ( aq ) → Cu( OH )2 ( s ) + 2 NaNO3 ( aq )Metathesis [ ii ] Cu( OH )2 ( s ) → CuO ( s ) + pee ( g )Dehydration [ iii ] CuO ( s ) + H2SO4 ( aq ) → CuSO4 ( aq ) + H2O ( l )Metathesis [ iv ] CuSO4 ( aq ) + Zn ( s ) → ZnSO4 ( aq ) + Cu ( s )Redox [ v ] 3 CuSO4 ( aq ) + 2 Al ( s ) → Al2( SO4 )3 ( aq ) + 3 Cu ( s )Redox [ vi ] While metathesis reactions come up to termination whenever unity of the components is removed from the etymon ( whether by the formation of a spoil or an non-water-soluble precipitate ), reactions [ v ] and [ vi ] proceed to...If you want to set off a full essay, set out it on our website: Ordercustompaper.com
