Distillation

Distillation is the separation of a solution by vaporising and condensing.

There are two ways you can remember this:

1) Still is in the name 'distillation' (THIS STILL) and a still is what they use in distillation.

A still is used in distillation that holds a solution before processing — The shape of the still creates a large surface area for the solution which maximises vaporisation.

Stills are used in the manufacture of alcohol in factories — Stills are also used in alcohol distillation plants (they’re usually made of copper).

2) Separation of a mixed solution by vaporising and condensing.

Before distillation a solution is held together — An easy way to remember this is to picture two columns being held together. While they are held, everything remains this still (distill).

This is the case until heat is applied, which causes everything to separate (separation).

Solutions are separated by vaporising and condensing the solution until elements break apart — Think of an alien vaporising the solution, causing the columns to separate.
