A lab report results section is a crucial part of any scientific study as it presents the findings and observations made during the experiment. It is important to clearly and accurately communicate the results of the study to the reader, whether it be a professor, peer, or member of the general public.
Here is an example of a lab report results section:
Title: Determining the Solubility of Potassium Chloride in Water at Different Temperatures
Introduction: The solubility of a substance is defined as the maximum amount of the substance that can be dissolved in a solvent at a given temperature. The solubility of potassium chloride (KCl) in water was determined at three different temperatures: 20°C, 40°C, and 60°C.
Materials and Methods: A 100 mL beaker was used for each temperature, and the appropriate amount of deionized water was added to each beaker. A thermometer was used to measure the temperature of the water, and the temperature was adjusted to the desired level using a hot plate. The appropriate amount of KCl was added to each beaker, and the solution was stirred until all of the KCl had dissolved. The solution was then allowed to cool to room temperature and the mass of the KCl was measured using a balance.
Results: The results of the experiment are presented in Table 1.
Table 1: Solubility of KCl in water at different temperatures
Temperature (°C) | Mass of KCl (g) | Mass of Water (g) | Solubility (g/100 mL) 20°C | 10.0 g | 100 mL | 10.0 g/100 mL 40°C | 12.5 g | 100 mL | 12.5 g/100 mL 60°C | 15.0 g | 100 mL | 15.0 g/100 mL
The solubility of KCl in water increased with increasing temperature. At 20°C, the solubility was 10.0 g/100 mL, while at 40°C and 60°C, the solubility increased to 12.5 g/100 mL and 15.0 g/100 mL, respectively.
Discussion: The solubility of KCl in water increased with increasing temperature, which is expected based on the solubility curve for KCl in water. At higher temperatures, the solubility of a substance typically increases due to the increased kinetic energy of the solvent molecules, which allows them to more easily dissolve the solute.
In this experiment, the solubility of KCl in water was determined at three different temperatures, and it was found that the solubility increased with increasing temperature. These results are consistent with the expected behavior of KCl in water and demonstrate the importance of temperature in determining the solubility of a substance.
Conclusion: The solubility of KCl in water was determined at three different temperatures, and it was found that the solubility increased with increasing temperature. These results are consistent with the expected behavior of KCl in water and demonstrate the importance of temperature in determining the solubility of a substance.
This lab report results section example demonstrates the clear and concise communication of the findings of the study. The table presents the data in an organized and easy-to-understand format, and the discussion section explains the significance of the results and relates them to the broader scientific context. It is important to carefully and accurately report the results of a scientific study in order to accurately communicate the findings and contribute to the body of knowledge in the field.
