On what principle of the following methods of separation based give one example of a mixture for each of the methods mentioned in which they are used

A. Sublimation,and

B. Chromatography

Sublimation:

The changing of a solid state directly into vapours on heating and vapours into solid on cooling is called sublimation.

The solid substance which undergoes sublimation is called as sublime.

The solid substance obtained on cooling the vapours is called sublimate.

The process of sublimation is used to separate those substances from a mixture which sublime on heating.

The substances like ammonium chloride, iodine, camphor, naphthalene, anthracene sublime on heating and can be recovered in the form of a sublimate by cooling their vapours.

Most of the solid substances do not undergo sublimation.

For Example :Substances such as common salt and, iron filing, chalk etc
Chromatography

It is a technique of separating two or more dissolved solids which are present in a solution in very small quantities.

By paper chromatography two or more different substances present in a same solution can be separated. Two or more substances are soluble in same solvent but their solubility may be different .

For Example :Black ink is a mixture of several coloured substances which can be separated by this method.
