Unformatted text preview: Atif Saleem, Chem 3AL, Section 101 Discussion: Experiment 3 Mixed Melting Points For Part I, I was given a vial # 220 with an unknown solid in it, and in order to find someone with the same solid as mine, I found the melting point range of my unknown solid. In the first approximation, I melted a small amount of my unknown solid at a rising temperature rate of 6 degrees Celsius per minute. This gave me an estimated 97-100° C which represents the time at which my solid began and ended its melting. Before observing my solids melting point a second time, I crushed it to a finer consistency, put in less than I did in the previous trial, and let the temperature rise by 2° C per minute. I got a more accurate melting temperature range of 98.9 – 100.9 °C this time, and I compared it with two other classmates. The first classmate, Emma, had a melting point range of 97.1- 98.3° C; upon mixing our solids and melting them, we attained a melting point range of 76 – 77.7° C implying that we didn’t have the same solid. The attained a melting point range of 76 – 77....
