Question

can we separate a mixture of camphor and napthalene by sublimation? Support your answer with reason.

Answer 1

no we cant seprate camphor and napthlene by sublimation because both substance are sublime when we heat both substance both camphor and napthelene will directly change into gas and no residue will left
we can seprate this by handpicking or crystillisation

Answer 2

hello there ...

Nahthalene is highly insoluble in water while ammonium chloride / camphor is not.

 We can add distilled water to the mixture to dissolve the ammonium chloride and then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity, therefore you can separate naphthalene from ammonium chloride.

hope helped !! :))
