Copper Lab

Dr. Jefferson Andrews Chemical Principalities - CHEM 1101 1 October 2008 Copper, the Funnest lab Ever. Abstract: This examine served as a test of our individual laboratory skills in carrying take up out some(prenominal)(prenominal)(prenominal) Abstract: chemic transformations involving slob. The experiment was successful in that the Abstract: percent soften was reasonable, and we were able to reanimate our slovenly person sample with Abstract: maximal efficiency ( we were able to reform all of the pig with which we began ). base: This experiment involved the detachment and purification of our desired harvest-feast ( copper ) from any chuck out side products. This was accomplished victimization several 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 thoroughgoing types of chemical reactions. Through these reactions, we performed several chemical transformations involving copper, and were able to bump our copper sample with supreme 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 weewee ( 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 ) + water ( 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 finale whenever unity of the components is removed from the termination ( whether by the formation of a spoil or an indissoluble precipitate ), reactions [ v ] and [ vi ] proceed to...If you want to make water a full essay, install it on our website: Ordercustompaper.com
