experiment #1 – Melting point
employees.oneonta.eduExperiment #1 Melting Point Page 2 Figure 1 - Melting Point Using Thiele Tube Filling the Capillary Tube Make sure the sample is dry. [This is not an issue in this experiment, but in the future you will want to determine the melting point of a solid you have just separated from a liquid by filtration.
Experiment 5 - Los Angeles Harbor College
lahc.eduAllow the temperature of the melting point apparatus to increase 1 C per minute starting from 120 C. Measure the melting point range of the aspirin product. The melting point range is the temperature when you first notice the aspirin crystals melting up until the temperature when no crystals remain. Day 3 – Titration Analysis 1.
