Chapter 4.4, Problem 14E

(a)

Interpretation Introduction

Interpretation:

The normal boiling point of acetone and ethyl acetate should be specified.

Concept Introduction :

The normal boiling point is temperature at which a liquid boils at 1 atmosphere of pressure (760 torr)

(b)

Interpretation Introduction

Interpretation:

The composition of the mixture of acetone and ethyl acetate which boils at 65 0C should be determined.

Concept Introduction :

In the boiling point diagram, the variation of the equilibrium compositions of the components in a liquid mixture with temperature is shown at a fixed pressure.

(c)

Interpretation Introduction

Interpretation:

The temperature at which the mixture begins to boil and the mole fraction of acetone in the vapor phase should be determined.

Concept Introduction:

In the boiling point diagram, the variation of the equilibrium compositions of the components in a liquid mixture with temperature is shown at a fixed pressure.

Caffeine can be extracted from tea bags using liquid-liquid extraction. After extracting the tea in hot water, sodium carbonate can be added to form the starting aqueous solution. In a separatory funnel containing 20 mL of diethyl ether, the same volume of aqueous solution will be added. The same procedure will be done in another separatory funnel but this time the organic solvent is hexane. Both separatory funnels will be shaken to release the pressure, and let stand to promote layer separation. The organic layers now containing caffeine will be separated into separate beakers. The beakers were then dried using calcium chloride (CaCl2). The beakers containing both solvents will be dried to obtain the isolated caffeine. Why is it important to release the pressure by venting out the separatory funnel? How will this affect the extraction when bypassed?

Homemade ice-cream is frozen by churning it in a bucket suspended in an ice-water-salt mixture. A typical mix calls for 1.80 kg of salt (NaCl) and 8.75 kg of ice. Compute the mole fraction of NaCl in this mixture after all the ice melts.
