Briana TurnerLab Report #5TA: Ryan WoodIntroduction:The purpose of this experiment was to observe the copper cycle: the series ofreactions that converts elemental copper to different chemical states and then back toelemental copper. The copper cycle is able to take place by utilizing multiple types ofreactions such as an oxidation reduction reactions in which there is a transfer of electronsbetween two species, a precipitation reaction in which two soluble salts form an insolublesalt, the dehydration of a base to for a base anhydride and water, as well as an acid basereaction which forms a salt and water.Experimental Methods:The procedure outlined in the General Chemistry Lab Manual for this experimentwas followed when this experiment was conducted (“General Chemistry Lab Manual”51-62). For the dissolution of copper oxide an additional 4 mL of sulfuric acid was addedto the solution, and a total of 3.51 g of zinc was used.Equations and Observations:Step 1:NO3¿2(aq)+2H2O(l)+2N O2(g)4H NO3(aq)+Cu(s)→Cu¿Reaction Type: Oxidation Reduction reaction
