Question

Differentaite between flash distillation and fractional distillation

Answer 1

Answer:

Distillation

1. Distillation is a process used to separate liquids with boiling points which comprise gaps around  50 degrees at least.

2. Every vaporization-condensation step is recognised as simple      distillation.

3. Used in the purification of seawater.

4. The experimental set up is simple. Needs a simple apparatus with two simple flasks and a condenser.

Fractional Distillation

1. Fractional Distillation is a process used to separate liquids with closer boiling points

2. In a method of fractional distillation, multiple simple distillation processes are carried out with small losses in one apparatus.

3. The experimental set up is complex. We need a complex apparatus with a fractioning column.

4. Used in crude oil refining
