Question

35. Differentiate between simple distillation and fractional
distillation.​

Answer 1

Answer:

Answer. 1, Simple distillation is the method used to separate substances in mixtures with significantly different boiling points, while fractional distillation is used for mixtures containing chemicals with boiling points close to each other.

Answer 2

Simple Distillation

• Distillation is a process used to separate liquids with boiling points which comprise gaps around  50 degrees at least.
• Simple distillation will have only one cycle of distillation i.e vaporization-condensation throughout the process.
• The experimental set up is simple. Needs a simple apparatus with two simple flasks and a condenser.
• Used in the purification of seawater.

Fractional Distillation

• Fractional Distillation is a process used to separate liquids with closer boiling points.
• The fractional distillation will have at least two cycles.
• The experimental set up is complex. We need a complex apparatus with a fractioning column.
• Used in crude oil refining.
