Question

Which of the following statements are true for simple distillation?​

I- It is used to separate immiscible liquids.​
II- The liquids must have a large boiling point difference.​
III- A mixture of water and acetone can be easily separated by distillation.

• A. I and II
• B. I, II and III
• C. II and III
• D. I and III

Answer 1

The correct option is C II and III

• The mixture of two miscible liquids can be separated by simple distillation method.​

So statement I is false.

• The liquids should have a boiling point difference of greater than 25 °C.​

​So statement II is true.

• The boiling point of acetone is ${56}^{o}C$, whereas that of water is ${100}^{o}C$. These liquids have a large difference in their boiling points. So, they can be separated using simple distillation.

So statement III is true.

Therefore, statements II and III are true.
