A student prepared five solutions of CuSO4, each with varying concentrations. This experiment aimed to understand the properties of copper sulfate and its behavior under different conditions. By preparing these solutions, the student could observe the color changes, solubility, and other characteristics of the compound.
The first solution was prepared by dissolving a known amount of CuSO4 in distilled water. This solution served as the reference point for comparison. The student then prepared four more solutions with increasing concentrations of CuSO4. Each solution was labeled with its respective concentration for easy identification.
The second solution had a slightly higher concentration of CuSO4 than the first, resulting in a darker blue color. This indicated that as the concentration of CuSO4 increased, the intensity of the blue color also increased. The student observed that the solution became more opaque as the concentration increased, suggesting a higher solubility of CuSO4 in the solvent.
The third solution, with an even higher concentration of CuSO4, exhibited a deeper blue color and was more opaque than the previous solutions. This confirmed the trend observed in the second solution, where an increase in concentration led to a more intense blue color and higher solubility.
The fourth solution, prepared with an even higher concentration of CuSO4, showed a very dark blue color, almost black, and was almost completely opaque. This indicated that the solubility of CuSO4 in the solvent had reached its maximum limit, and any further increase in concentration would result in precipitation.
The fifth solution, with the highest concentration of CuSO4, turned out to be almost completely black and completely opaque. This confirmed that at this concentration, CuSO4 had become highly insoluble in the solvent, leading to the formation of a solid precipitate.
Through this experiment, the student gained valuable insights into the behavior of CuSO4 solutions under varying concentrations. The color changes, solubility, and precipitation observed provided a clear understanding of the properties of copper sulfate and its application in various fields, such as agriculture, medicine, and industry.
