what is sublimation and distination
DISTILLATION
In any solution (mixture of two or more liquids) liquids having sufficient differences in boiling point can be separated by heating at different temperature
OR
volatile liquids are separated from non volatile impurities
if the boiling point difference is very small in fraction then it is called as FRACTIONAL DISTILLATION
SUBLIMATION
Solid substance change to vapour, without undergoing liquid state
hence we can seperate out sublimable substance from non sublimable impurities
example of sublimable substance IODINE,AMMONIUM CHLORIDE , NAPHTHALENE, CAMPHOR
