Dear user,
There are many techniques or principle used in separation of mixtures.They are :
1)Filteration
‚ÄčThis is based on difference in the size of the particles.
2)Distillation
This is based on the difference in boiling points of the materials.
3)Evaporation
This is based on the difference in boiling points of the substance that is it is generally used for solid form.
4)Decantation
‚ÄčIt is a process used to separate liquids and solids.Generally a liquid layer is removed.
