Introduction Copper is an extremely significant element in many ways whether it be biological, environmentally, or even economically, and each of its many forms has unique characteristics that serve many different purposes. In this experiment, chemical reactions were conducted on copper that represented its reactivity in different chemical environments. Therefore, the purpose of this experiment was to explore the copper cycle through the identification of different reaction types that occurred in it and that eventually lead up to the regeneration of the original product.
Materials and Methods The preparation of the experiment started off by placing a hot plate on a ring stand. A 50 mL beaker was then attached to the iron ring and placed on top of the hot plate. This was followed by preparing a fume hood. The hood was completed by connecting a funnel to a hose leading to an aspirator. Lastly, the funnel was clamped to the ring stand right above the beaker. In the first step of the cycle in the experiment 0.2471 grams of copper turnings were weighed on a tared weigh boat using an analytical balance. The turnings were then placed in the 50 mL beaker on the hot plate. After the aspirator was turned on, between 4 and 5 mL of 6 M HNO3, previously obtained in a 10 mL graduated cylinder, was added to the beaker. In the second step of the cycle, 10 mL of distilled water were added to the beaker after the aspirator funnel was removed. Afterward, 6 M NaOH was added dropwise to the…
