Title of Experiment: Experiment 3D Mixture Melting Points

Purpose or Aim: This says exactly what the goal of the experiment is. It may consist of one or more parts. Based on what is stated in the procedure, you should have a very good idea as to what the point of the experiment is. Explicitly and briefly state all in this section.

Examples: 1. To recrystallize an impure sample of benzoic acid; 2. To determine the melting point of salicylic acid

Introduction: This explains the theory behind the experiment. Give some general background as to what the experiment is about. Include definitions of any key concepts that are an important part of the experiment.

This approach can be applied across all topics being covered. Materials: List glassware, chemicals and equipment/instrumentation used in the experiment.

Procedure: Write a step-by-step procedure of the experiment as outlined in the video. Use a flowchart if possible.

Results and Calculations: Report results from experiment. Tables can be used, also show sample calculations.

Discussion: Analyze the data you obtained in your experiment. Relate them to the background information and concepts of the theory behind the experiment. Indicate what information you have gathered based on the results of your experiment. Try to explain (reasonably) anything that may have gone wrong with the experiment, which may have led to inaccurate results. Where applicable, compare your result to what may be the true/accepted or expected result, and try to defend why your result is the way it is, whether good or bad. This is also an opportunity to mention any sources of error (tangible ones), that you know caused the experiment to turn out differently than expected. A discussion is meaningless if there is no mention of the results (the actual numbers where applicable) etc.

Conclusion: This is directly related to your purpose. Restate the purpose of your experiment and the results in as concise a manner as possible. DO NOT USE THIS TO SUMMARIZE OR REPEAT YOUR DISCUSSION.

References: (If used) The melting points in the screenshots/pictures I provided are complete on the first attachment paper where the professor gave us his melting points, so that part is completed. I just need the Lab write up format complete from the Title through the Conclusion. Or references if you used any. Thank you!

Title of Experiment: Determination of Melting Points of a Mixture of Organic Compounds

Purpose or Aim

The primary objective of this experiment is to determine the melting points of a mixture of organic compounds to assess their purity and composition. By analyzing the melting behavior of the mixture and comparing it with pure samples, we aim to understand the effects of mixture components on melting points and evaluate the purity of the samples.

Introduction

The melting point is a fundamental physical property indicating the temperature at which a solid becomes a liquid. In organic chemistry, melting points are commonly used to identify and assess the purity of compounds. A pure substance exhibits a sharp melting point over a narrow temperature range, whereas an impure sample displays a depressed and broadened melting point range. When two compounds are mixed, the melting point typically decreases compared to the pure components, especially if they are immiscible or have different structures. This experiment leverages this principle to analyze mixtures and infer their composition based on melting point behavior.

Materials

• Test tubes and capillary tubes
• Melting point apparatus
• Impure samples of organic compounds
• Pure samples of organic compounds
• Glass stirring rods
• Crucibles
• Thermometer

Procedure

1. Prepare small amounts of the pure compound and the mixture in separate capillary tubes by filling each tube with a small amount of sample and packing it carefully.
2. Place the capillary tubes in the melting point apparatus, ensuring proper contact with the temperature sensor.
3. Gradually heat the apparatus and observe the sample through the magnifying viewer.
4. Record the temperature at which the first signs of melting appear and the temperature at which the sample is completely melted.
5. Repeat the process for all samples, including the pure compounds and the mixture.

Results and Calculations

The melting points obtained are summarized in the following table:

Sample calculation: The depression in melting point for the mixture indicates partial miscibility or impurity presence, consistent with the theoretical expectations based on the composition.

Discussion

The observed melting points reflect the purity and composition of the samples. The pure compounds exhibited sharp melting points, indicating high purity. The mixture showed a lower and broader melting point range, suggesting the presence of components that interfere with each other’s crystalline structure. The melting point depression aligns with the concept that introducing impurities or forming mixtures lowers the melting point of a substance. Sources of error could include temperature calibration issues or improper packing of the samples, which might have influenced the precise readings. These results demonstrate the importance of melting point analysis in organic compound characterization and purity assessment.

Conclusion

The experiment successfully demonstrated the effect of mixing organic compounds on their melting points. The mixture displayed a depressed and broadened melting point range compared to pure samples, confirming the theories of melting point depression and impurity effects. Melting point analysis remains a valuable tool for identifying and assessing the purity of organic compounds in laboratory practices.
