Sulfate

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…

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…

for the sulfate test due to the formation of a white precipitate, indicating the presence of a sulfate ion. For the sulfate test the unknown solution, potassium sulfate, and combining it with hydrochloric acid and barium chloride. If a sulfate anion was present in the unknown solution, then the anion would combine with the barium and form the precipitate, BaSO4, and the chlorine ion would combine with the unknown’s cation. In this case a sulfate anion was present in the unknown so the sulfate…

hydrogen peroxide increases. The presence of the anions decreases the rates of the phenolic compounds, the sulfates influence in a smaller degree. For phenol and 2-nitrophenol the difference in slope or degradation rates for chloride and sulfate are 0.71 and 0.55, and only 0.16 for 2-chlorophenol. The presence of chloride inhibits in greater proportion the formation of hydroxyl radicals than the sulfate , this can be due to some free radicals that are scavenged and the formation of some…

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 was…

two test tubes, a beaker, about 4 grams of magnesium sulfate (MgSO4), about 4 grams of copper sulfate (CuSO4) and a burner. First, we measured the mass of the beaker and the test tube on the triple beam scale. We then filled one test tube with some copper sulfate. We placed it into the beaker on the scale to find its mass and recorded the mass of the total to make sure we had about grams of copper sulfate. After we had the mass of the copper sulfate amount, we heated it up over the burner until…

Phenols Degradation by Fenton Reaction in the Presence of Chlorides and Sulfates Siedlecka et al. (2005) also studied a series of phenol compounds present in wastewater. These compounds, as mentioned above, are widely used therefore are commonly found in wastewater derived from different industries such as petrochemical, food or resin manufactured. Since common biological treatment for these kinds of compounds is not feasible, is important to develop new technologies to treat these…

test tube A, the reactants are copper sulfate and magnesium. Magnesium is an element and copper sulfate is a compound. In a single displacement reaction, a reactive element displaces another less reactive element in a compound. After checking the activity series for metals, I know that magnesium is more reactive than copper sulfate; so that in the reaction, magnesium takes place of the copper element in copper sulfate to produce copper metal and magnesium sulfate. During the reaction, a…

Question What is the formula of hydrated copper (II) Sulfate, CuSO4 • xH2O? Hypothesis When hydrated copper(II) sulfate is heated, the high temperature will cause the water and copper(II) sulfate to decompose forming anhydrous copper(II) sulfate and water (vapour). The reaction which will occur is decomposition. Materials 1. 400 mL beaker 2. beaker tongs 3. Hot plate 4. Scoopula 5. Electronic balance 6. Glass rod 7. 3g hydrated copper(II) sulfate 8. 3g hydrated barium chloride 9. ceramic bowl…

solubility test of the unknown compound determined that the compound was soluble in water (H2O). The other known salts that were tested that were also soluble were all of the sulfates and NaCl. These were the only salts tested, because before this experiment it was determined by the flame test that the compound was a sulfate (explained later). This information means that the unknown compound is polar, because it is soluble in water. This is because H2O, the solvent, is polar, and the solute,…
