Data Table:
Boiling Point Trial 1 Trial 2 Trial 3
Temperature when the last bubble has emerged ___83_˚C __82__˚C __82__˚C
Average temperature from all three trials ___82.33_˚C
% error ___.0849_%
Melting Point Trial 1 Trial 2 Trial 3
Temperature when the acetamide melts __82__˚C _81___˚C __82__˚C
Average temperature from all three trials ___81.66_˚C
% error ___.815_%
Conclusion:
The purpose for this experiment is to analyze the melting and boiling point of specific types of liquid and solid. It is useful to know their melting and boiling point of a substance to state whether or not such substance is pure or if it is combination of different chemcials.
I was able to learn how to determine the melting point and boiling point of a substance by analyzing its temperature whenever acetamide turned into a liquid and when Isopropyl started to emerge bubbles. Since acetamide and lsopropyl had the similar melting; boiling points, it is to my understanding that the melting point and boiling point depends on the properties of the substance, not the state of its matter.
During the experiement, safety with tools and chemicals were crucial. The glass of capillary tube was very fragile, which was difficult during the process of breaking down the acetamide. cautious appoarch was made whenever dealing with burner-fuel. Acetamide was very small and was hard to tell their location whenever I tried to break them down in to small pieces to put inside the capillary.
There were several errors which could have affected the experiment. The tap water I used to heat the liquid and solid may had different properties inside, which can cause the boiling point to be off. Pure H2O is recommeneded to conduct more precise measurement. The capillary tube I used was too fragile whenever it was used to break down the acetamide.
