Lab report Questions What will happen when zinc is placed in copper (II) sulfate? What will happen when copper is placed in copper (II) sulfate? Prediction It is predicted that when you place zinc and copper (II) sulfate a reaction will occur, resulting in a precipitation. The prediction about the copper (II) sulfate and copper is that nothing will happen. Hypothesis It is hypothesised that when zinc is placed in aqueous copper (II) sulfate, a single displacement reaction will occur as the…

Percent Copper In Brass Lab Conclusion Emily Oleisky The purpose of this lab was to observe the amount of light a solution absorbs, and use the relationships in the Beer-Lambert Law to determine the quantity of a certain compound within a complex sample. First, the relationships between wavelength, concentration, and absorbance were determined. This lab focused on identifying the absorption of copper in various brass samples, and finding the percent copper in brass. In the first activity of the…

Experiment 2: Copper/Iron Stoichiometry Abstract: The purpose of the Copper/Iron Stoichiometry lab was to determine which of the two possible iron sulfate compounds formed when reacting aqueous copper(II)sulfate with solid iron metal. The techniques used in this lab were weighing by difference, quantitative transfer, and vacuum filtration. At the end of the experiment it was found that iron was the limiting reactant and iron(II)sulfate was a product of the reaction between 7.0002g of…

what is the actual percent yield of copper produced in grams/milliliters from the reaction of 2 g of solid copper (II) sulfate pentahydrate and approximately .25 g of aluminum foil in 10 mL of water versus the theoretical yield of copper metal. The hypothesis stated that if a reaction occurs between 2 g of solid copper (II) sulfate pentahydrate and 2 mL of 6 molar hydrochloric acid with approximately .25 g of aluminum foil, then the actual percentage yield of copper produced will be at least 25%…

Nicole is the Ramen spectroscopy expert in her research group. She wondered whether she could use Ramen spectroscopy to study Copper 3 hydroxide vibrations. However, Copper 3 hydroxide is challenging to study due to its reactivity. She proposed the work to her advisor who rejected the idea because "it just doesn 't work". From there, she began diligent research in two parts (1) to prove to her advisor that Ramen Spectroscopy should, in theory, be able to measure the vibrations and (2) to map…

Avogadro’s number. Avogadro’s number will be determined by setting up an electrochemical cell to oxidize a copper electrode. The results of the amount of copper deposited and the average current used will be used to calculate a value for Avogadro’s number. Techniques used: In this experiment, different techniques will be used to collect the required data, such as taking the mass of the copper electrode on an analytical balance, preparing the electrodes, using LabQuest, and assembling an…

deep blue pigment which was originally made by grinding lapis lazuli(deep blue stone) into a powder. Lead-tin-yellow is a yellow pigment also known as "Yellow of Old Masters". Malachite is a copper carbonate hydroxide mineral. Verdigris is a green pigment made through a process which that occurs when copper, brass, or bronze, is exposed to air over a period of time.Vermilion is a red pigment made from a powdered mineral called cinnabar. A couple examples of these materials used in the painting…

A. Significance Copper is one of the most abundant transition metals in the human body and its redox characteristics make copper an important cofactor in many enzymes. Copper containing enzymes are important for tissue generation, synthesis of neurotransmitters, and catalysis of the electron transfer reactions.1 Because of its diverse functions, copper homeostasis deficiency is linked to many diseases. A prominent example is Wilson’s disease with a prevalence of approximately 1 case in 30,000…

PROCEDURE Experiment required: copper (II) sulfate hydrate, 2 crucibles, electronic mass balance, bunsen burner, iron ring, crucible tong, clay triangle, wire gauze, retort stand, 1. Individuals should wear goggles on and tied hair back before the experiment started. 2. The mass of an empty crucible cover was measured. 3. Approximately 2.00g of copper (II) sulfate hydrate samples was taken out and put into the crucible. 4. The mass of the crucible cover and copper (II) sulfate hydrate samples…

local hardware store to purchase a galvanized nail and small piece of copper wire. My grand total was very affordable at 20 cents. 1. One large orange 2. One 2-inch-long galvanized nail 3. 2-inch-long copper wire 4. String of holiday Christmas lights 5. Needle nose pliers Procedure To start this lab experiment, I gathered all the supplies needed and placed them onto my kitchen counter (see picture). First, I took the copper wire and stripped off the insulated coating with the pliers. Next, I…
