Draw a line with a pencil at about three centimetres height from the base of this paper. Place a drop of black ink on the pencil line. Choose three or four dyes, for e.g., red, blue, g..

. The liquid so obtained is called the distillate and it is collected in a clean container. While distilling a solution, heating should be stopped much before the distilling flask becomes dry, otherwise it may break (Fig 4.8..

Liquids that are immiscible in each other differ in their densities and so can be separated by making use of a separating funne..
