Technique Report -Distillation and Boiling Point- Experiment 1 Experimental determination of ethanol boiling point gives the following results: Trial В.Р (°C) 75.6 77.1 1 2 76.3 The value for the atmospheric pressure in the laboratory was measured to be 711 mmHg. 1. Determine the corrected boiling point of ethanol. Show your work. 2. Calculate the % error compared to the reported standard value for ethanol boiling point which is 79.0 °c. 3. Discuss two potential reasons that might result in errors in b.p. measurements (please do not include reasons such as: thermometer not working properly or any other instrumental errors).
