Chapter 4.4, Problem 10E

Can a mixture of trichloromethane and propanone be separated into the pure components by fractional distillation? Explain

Describe the DISTILLATE AND RESIDUE in the separation of the ethanol-water mixture in simple distillation.

You were given a mixture of two miscible solvent A and B that you are tasked to separate. You know that solvent A has a boiling point of 49 oC while solvent B has a boiling point of 174 oC. Which of the listed method would overall be the most efficient?    Fractional distillation Recrystallization Solid-liquid extraction Liquid-liquid extraction Simple distillation Acid-Base extraction

Why is it important to perform a fractional distillation slowly? What happens if a fractional distillation is done very quickly by rapidly raising the temperature of the heat source?

How can the temperature and the vapour pressure in a fractional distillation be effectively controlled

explain why the boiling point of a two component mixture rises slowly throughout a simple distillation when the boiling-point differences are not larger

Describe in words and by means of complete chemical equations, how a mixture of 1.25 g of benzoic acid tertbutylbenzene can be separated by applying the separation of 2 components by liquid-liquid extraction.

What will be the composition of the vapor when a mixture containing 0.30 of A was subjected to fractional distillation with two theoretical plates?   a 0.72 A; 0.28 B   b 0.87 A; 0.13 B   c 0.50 A; 0.50 B   d 0.30 A; 0.70 B

Explain the importance of using a thermometer in the simple distillation setup. Enumerate the characteristics of a substance for it to be separated from the heterogeneous mixture by steam distillation. How does steam facilitate the distillation of essential oils? Discuss some applications of simple distillation and steam distillation. Explain why you can use each method for the chosen application. What is the most dominant intermolecular forces of attraction that exist between: a. water and limonene, the major monoterpene component of lemon essential oil? b. water and constituent ions of sodium chloride? 6. Based on your answers in number 5, which pair (water-limonene or water-sodium chloride) exhibits a stronger attraction between their molecules/ions? 7. Describe what happens during the salting-out process in terms of the intermolecular forces of attraction involved as mentioned in your previous answers.
