1. In this distillation experiment we start the experiment with10 mL of liquid mixture ofcyclohexane and toluene. However, it isnot possible to obtain all 10 mL back under thecurrent procedureparticularly for fractional distillation. Explain why that is thecase for distillation and inparticular for fractional distillation.
2. How could you modify theexperiment and collect all 10 mL of thestartingmaterials.
3. Plot a theoreticaldistillation curve of temperature (y-axis) vs. volume in mL(x-axis) fora 15 mL of a mixture containing 60% 1-propanol and 40%2-propanol. Are these twocompounds easier to separate bydistillation than cyclohexane and toluene? Explainyouranswer.
4. In this experiment you were asked to collect two fractions andearly fraction and a latefraction. Which of the two fractions wouldbe richer in cyclohexane? Would there be adifference between thepercent of cyclohexane in the fractions collected fromfractionalvs. simple distillation.
5. What method of purification would you use to purify methanolfrom a solution ofmethanol and NaCl? Be specific and explain yourchoice of method.
