Melting point determination lab report

28/03/2021 Client: saad24vbs Deadline: 2 Day

Chelsey Grasham

Lab Report Assistant

Purpose: The purpose of this experiment was to determine melting and boiling points of certain substances.

Procedure: For this experiment, I collected different substances, heated them, boiled them, and observed them while recording data.

Conclusion: From this experiment, I learned that different substances have different boiling points and that the boiling/melting point of a substance can tell you about its identity.

Exercise 1: Determination of a Melting Point

Data Table 1. Melting Point of Tetradecanol.

Questions

A. Describe your results for the melting point of tetradecanol. Were your results consistent? What was the range of values? My results remained fairly consistent and my values only ranged from 38-40 degrees Celsius.

B. Describe what occurs to the particles of a substance when the substance melts. Explain why this occurs. As a substance melts, the bonds begin to lose their strength and in turn, the substance turns into a liquid.

C. When performing this experiment, when is the tetradecanol in a condensed phase? Explain your answer. In this experiment, tetradecanol is in a condensed phase when it is a solid/going into the liquid stage. This must be due to the fact that the molecules are really close together.

D. Based on your observations of tetradecanol when it reformed a solid after melting, does tetradecanol form a crystalline or amorphous solid? Explain the difference between these two terms as part of your answer. I do not think tetradecanol is a crystalline solid because those kinds of solids usually go back to their solid form, from liquid the liquid form, in a very long time. This is not what happened. I believe it is a amorphous solid because it went back to a solid almost immediately.

E. Give some examples of how it might be useful to know the melting or boiling points of a substance. Think in terms of both scientific and commercial/industrial settings. Melting and boiling points are very important to know. For example, in commercial industries, like when jewelry is made, it is beneficial to know the melting points of the metals so they will be able to melt, and form the metals not jewelry. In a scientific point of view, it is important to know for safety and hazardous reasons.

F. Describe any possible sources of error for this exercise. Sources in error could include reading the thermometer incorrectly, setting the experiment up incorrectly, or not allowing things to heat for the time allowed.
