What is sublimation in chemistry?
SUBLIMATION is the physical property of some substances to pass directly from the solid state to the gaseous state without the appearance of the liquid state. Not all substances possess this characteristic. If one component of a mixture sublimates, this property may be used to separate it from the other components of the mixture.

2 , sand), sodium chloride (NaCl, table salt), and ammonium chloride (NH 4 Cl), from a mixture of these solid compounds. Three commonly- used methods of separation are given below: (a) SUBLIMATION Sublimationis the process by which a solid changes from the solid to the gaseous state directly without forming a liquid.
Can a mixture be separated into its components?
Although these and other characteristics can be used to identify a particular substance, we will be concerned, in this experiment, with the separation of a mixture into its components, not with the identification of the substances. Techniques used to separate mixtures rely on differences in the physical properties of the components.
Which of the following substances sublime?
Iodine (I2), naphthalene (C10H8, mothballs), ammonium chloride (NH4Cl) and dry ice (solid CO2) are some substances which sublime. CHROMATOGRAPHY is the process of separating a mixture by the distribution of its components between two phases, one phase being stationary and the other phase moving.
