Question

b. Which component should distill off first? c How does the boiling point of that liquid compare to temperature measurements at the beginning of both simple and fractional distilation? d. What does this comparison tell you about the composition of the intial distlation from both simple and fractional diestilation? e Using vour tractional distilation plot, estimate the final volume of ethanol produced in the fermentation 6. Given your responses to the previous questions, provide a sketch of what you would expect a boiling point versus distilate volume plot of the fractional distilation of a 3:1 mixture of cyclohexane toluene to look like, assuming a 35 mL sample was distilled 7. Do your conclusions about the graph data correlate with the purity determinations you performed on the two collected samples? 8 Could simple distilation be used to isolate a pure sample? If so, in what type of situation would this be possible? 9. If you were trying to separate two compounds with very close boiling points how could you increase the efficlency of a fractional distilation in order to separate those compounds?
#8- could simple distillation be used to isolate a pure sample? if so, in what type if situation would this be possible?

thank you!!

Answer 1

Yes, simple distillation could be used to isolate a pure sample.

Simple distillation is a process to separate two liquids with different boiling points. For example: sugar and water solution can be separated using simple distillation.

This process of simple distillation is only possible when there is a minimum difference of 50 degrees in the boiling temperatures of two components of a solution.
