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 projection 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 boar sample with Abstract: maximal efficiency ( we were able to come up all of the slovenly person with which we began ). Introduction: This experiment involved the insularism and purification of our desired product ( copper ) from any cast aside side products. This was accomplished using 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 fundamental typ es of chemical reactions. Through these reactions, we performed several chemical transformations involving copper, and were able to recover 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 body of 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 ] CuSO4 ( aq ) + Zn ( s ) → Z! nSO4 ( 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 achievement 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, monastic order it on our website: OrderEssay.net
