Question

write the bacic principal of
a) submilation
b) crystallization​

Answer 1

The principle behind the crystallisation is that the amount of solute that can be dissolved by a solvent increases with temperature. In crystallisation, the impure substance is dissolved in a suitable solvent to reach its nearly saturated solution at a temperature higher than the room temperature.

Sublimation is a process in which a solid turns directly into gas without passing into liquid state. It works on the principle that solids have a weak intermolecular force hence a higher vapour pressure which converts it into directly vapour state.

Answer 2

Explanation:

Sublimation is a process in which a solid turns directly into gas without passing into liquid state. It works on the principle that solids have a weak intermolecular force hence a higher vapour pressure which converts it into directly vapour state.

The principle behind the crystallisation is that the amount of solute that can be dissolved by a solvent increases with temperature and the fact that the solubility decreases with temperature. ... If the cooling is slow enough, the solvent forms crystals (some hydrated) on any surface like the inside of the beaker.
