Copper(II) sulfate

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 zinc is in its elementary form. Because it has a higher reactivity, it will probably displace the copper from copper (II) sulfate and a precipitation will be present. It is hypothesised that no reaction will occur between the copper (II) sulfate and the…

I’m contacting you about the concentrations of the two copper (II) sulfate solutions that you were unable to correctly identify. The good news is that, for both samples, we were able to accurately determine their concentrations using Beer’s Law, a well-established law that governs the relationship between a solution’s concentration and the amount of wavelength the solution can absorb under standard conditions. Before going any further, though, let me fill you in on some of procedures and…

The primary purpose of this experiment was to determine the concentration of solutions of copper (II) sulfate using visible spectrophotometry and Beer’s law. In this experiment, we used Beer’s law, which states that absorbance, i.e. the amount of light absorbed by a solution, is equal to the molar absorptivity of a compound, times the path length of the cuvette, times the concentration of the solution. First, we measured the absorbance of a cuvette filled with water, then calibrated the…

color as soon as the cupric sulfate dissolved. Prior to this 1.127 grams of Zinc was gathered along with Hydrochloric acid. Both the Zinc and Hydrochloric acid were poured in gradually creating a reaction. A stirring rod was used to stir this while the reaction occurred. Figure 2 shows the reaction in action. Before long less Zinc became visible at the bottom of the beaker. Copper became visible at the bottom of the beaker all at the same time. The bottom of the beaker released bubbles, or…

The testable question asked 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…

Determining the Chemical Formula of a Hydrate 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…

Title The Copper Reaction Cycle demonstrated in the experiment shows that copper can transform into different states of matter, while still conserving mass and returning back to its original room temperature solid state. Authors Makenzie Roybal * and Erin Wimberley Section CHEM 111-554 Introduction A topic of allure to many scientists is how high levels of copper intake can result in the disruption of human metabolism, and how it can degenerate the biological well being of ecosystems. The…

Cu Again: Reactions of Copper Lynna Jezek*, Long Nguyen CHEM 111-502 Introduction: The element copper has proven to be of great use to human civilizations through time; from the first bronze smelted by the Sumerians to copper’s practicality in today’s industry-driven world, copper has become essential to human life. Copper’s use in industry (such as its great conductivity of heat and electricity) has driven many scientists to study the Copper Cycle, or how copper behaves as a response to…

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…

Sarah Bounab BQD 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…
