To separate CAMPHOR from a mixture of camphor and salt, the most appropriate method is:
ASublimation, since camphor sublimes directly
BFiltration through a fine sieve
CCrystallisation by slowly cooling solution
DMagnetic separation with a strong magnet
Answer & Solution
Correct answer: A. Sublimation, since camphor sublimes directly
Sublimation separates a solid that sublimes (camphor, naphthalene, ammonium chloride, iodine) from one that doesn't (salt). Heat the mixture; camphor evaporates as vapour and is collected on a cool surface above.
