Summarize the results of the experiment
During the analysis, the onset of the boiling point of the substance is determined. During the analysis, a thermometer reading of the mercury column is set when 5% of the substance is expelled, and then every 10% is expelled, then 95% is expelled, and the boiling point of the substance is finally determined — the thermometer reading.
To plot the results graphically, we determine the temperature readings along the ordinate axis on the paper, and the volume readings along the abscissa axis. The beginning of the boiling temperature corresponds to the indicator "O" of the driving volume.
The difference between two analyzes performed by the same student under the same conditions should not exceed the following indicators:
- at the beginning of the boiling temperature 40C
- final and intermediate boiling points 20C and 1 cm3
-residual volume -0.2 cm3.
