Question 1: Which of the following statements is true about azeotropic distillation?

(a) It is a type of fractional distillation.
(b) It is used to separate components with large boiling point differences.
(c) It involves the addition of a third component to break the azeotrope.

Question 2: What is the purpose of adding a third component in azeotropic distillation?

(a) To increase the boiling point of the mixture.
(b) To decrease the boiling point of the mixture.
(c) To break the azeotrope and allow for separation of the components.
(d) To make the distillation process faster.

Question 3: Which of the following is an example of an azeotrope?

(a) Ethanol and water.
(b) Hydrochloric acid and water.
(c) Acetone and water.
(d) All of the above.

Question 4: In azeotropic distillation, which component is added to the mixture to break the azeotrope?

(a) A solvent.
(b) A catalyst.
(c) A third liquid.

Question 5: Which of the following is a disadvantage of azeotropic distillation?

(a) It requires the addition of a third component.
(b) It is a slow process.
(c) It cannot be used to separate components with large boiling point differences.
(d) It is not effective in separating components with similar boiling points.

Question 6: Which of the following is a method of breaking an azeotrope in azeotropic distillation?

(d) Heating the mixture to a higher temperature.

Question 7: What is the difference between a minimum boiling azeotrope and a maximum boiling azeotrope?

(a) A minimum boiling azeotrope has a lower boiling point than either of its components, while a maximum boiling azeotrope has a higher boiling point.
(b) A minimum boiling azeotrope has a higher boiling point than either of its components, while a maximum boiling azeotrope has a lower boiling point.
(c) A minimum boiling azeotrope has a constant boiling point and composition, while a maximum boiling azeotrope has varying composition.
(d) A minimum boiling azeotrope is easier to separate than a maximum boiling azeotrope.

Question 8: Which of the following is a common third component used in azeotropic distillation?
