Question

Acetone and carbon tetrachloride mixture can be separated by which method

Answer 1

This mixture can be separated by simple distillation technique.

Answer 2

Fractional distillation is the best method for the separation of Acetone and carbon tetrachloride mixture.

• This technique is used for the separation of miscible liquids which differ slightly in their boiling points.
• Acetone and carbon tetrachloride are miscible.
• The boiling point of acetone is 56°C and that of carbon tetrachloride is 76°C
• Simple distillation works only if the difference in boiling point is above 100°C.
• Repeated vaporization and condensation happen in the fractionating column and the most volatile substance that is acetone condenses first and leaves the column.
