Copper Lab

Dr. Jefferson Andrews Chemical Principalities - CHEM 1101 1 October 2008 Copper, the Funnest Lab Ever. Abstract: This experiment served as a test of our individual laboratory skills in carrying take up out some(prenominal) Abstract: chemical transformations involving slob. The experiment was successful in that the Abstract: percent yield was reasonable, and we were able to reanimate our sloven sample with Abstract: maximal efficiency ( we were able to recall all of the squealer with which we began ). Introduction: This experiment involved the pullout and purification of our desired product ( copper ) from any discarded side products. This was accomplished using some(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 fundamental types of chemical reactions. Through these reactions, we performed several chemical transformations involving copper, and were able to recover our copper sample with level best 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 water ( 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 ) + H2O ( g )Dehydration [ iii ] CuO ( s ) + H2SO4 ( aq ) → CuSO4 ( aq ) + H2O ( l )Metathesis [ iv ] Cu! SO4 ( 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 finis whenever unity of the components is removed from the solution ( whether by the formation of a spoil or an insoluble precipitate ), reactions [ v ] and [ vi ] proceed to...If you want to get a full essay, erect it on our website: BestEssayCheap.com
