The purpose of this lab is to demonstrate that the product of a chemical reaction depends on what is present at the time of that reaction. When a copper wire is introduced into an aqueous silver nitrate solution, a single replacement reaction occurs. When the copper is first oxidized, the solution is very concentrated, and the Cu 2+ product is initially coordinated to nitrate ions from the nitric acid, giving the solution first a green, and then a greenish-brownish color. Randy Sullivan, University of Oregon 6 a) and 3D (Fig. Essay Sample Check Writing Quality.
