What is fractional distillation used for?
Fractional distillation is used to separate mixtures of
liquids with different boiling points.
What is the main principle behind fractional distillation?
The principle behind fractional distillation is the
difference in boiling points of the components in a
mixture.
What equipment is essential for fractional distillation?
The essential equipment includes a distillation flask, a
fractionating column, a condenser, a thermometer, and a
collection flask.
Why is a fractionating column used in fractional
distillation?
The fractionating column increases the surface area for
repeated condensation and evaporation, allowing better
separation of components.
What property of liquids determines their separation
during fractional distillation?
The boiling points of the liquids determine their
separation during fractional distillation.
, How does temperature change in the fractionating
column during fractional distillation?
The temperature decreases as you move up the
fractionating column.
Why is the mixture heated gradually during fractional
distillation?
Gradual heating ensures that each component vaporizes
at its boiling point, allowing proper separation.
What happens to the vapor when it reaches the
condenser in fractional distillation?
The vapor cools and condenses back into a liquid in the
condenser.
What type of mixtures can be separated using fractional
distillation?
Fractional distillation separates mixtures of miscible
liquids with close but distinct boiling points.
Why is fractional distillation more efficient than simple
distillation for certain mixtures?
Fractional distillation is more efficient because it provides
multiple stages of condensation and evaporation within
the fractionating column.
What is the role of the thermometer in fractional
distillation?
