Question

Enumerate any two differences between simple distillation and fractional distillation

Answer 1

Distillation is a separation technique that is used to purify a liquid or a mixture of liquids by heating followed by cooling. When a mixture of liquids is heated, the components which have different boiling points go into gaseous phase at different instances. Condensation of the vapour allows it to be liquefied and thus, different components can be separated. There are several different distillation techniques adapted according to the composition of the liquid mixture. These are simple distillation, fractional distillation and steam distillation. The main difference between fractional distillation and simple distillation is that simple distillation separate liquids with boiling point gaps of at least 50 degrees whereas fractional distillation separates liquids with closer boiling points.

Answer 2

HEY MATE HERE IS YOUR ANSWER

(i) SIMPLE DISTILLATION

• It can be used if the liquids to be separated differ in their boiling points by more than 25∘C. If the difference is less, than fractional distillation can be used.

• It is often used to separate the liquid substance from the solid substance. Doing such separation with fractional distillation is not sensible.

(ii) FRACTIONAL DISTILLATION

• Column is needed for fractional distillation but not for simple distillation.

• It is used to separate components of a mixture of miscible liquids.
