vapour pressure of common salt is higher... hence it cannot be sublimed...
purified
Rock salt (impure salt) is frequently colored.
Camphor is a molecular compound, with a molecular formula C10H16O. Because it is molecular and the solid is "held together" by inter-molecular forces it has a lower melting point 175 C and boling point 204C than sodium chloride mp 800+C. bp 1400+ C. Under gentle heating solid camphor has a a reasonable vapor pressure and sublimes (no melting or boiling required -as it is flammable care is needed.) Sodium chloride a giant ionic lattice held together by strong electrostatic bonds when under heated gently has virtually no vapor pressure and does not sublime.
eeeek,i would say salt water.Do not take my word.I'm just assuming because salt is a solute that absorbs any liquid.So while the water is evaporating the salt is absorbing as well.well I'm not sure,but hopefully that helps a little to you hypothesis.
Yes. The water will evaporate and leave the residue of salt or sugar. A process crystalization is also there from which solids are purified from liquids by heating and then cooling, leaving purified crystalals.
Because salt doesn't sublime !
sublimation
Sodium chloride is not purified by sublimation.

Purified salt may not be safe to eat because it may have the bacteria of the rock salt on it still. To make it pure you should boil the bacteria off the salt after it has been purified.
Salt that has had any contaminates removed.
It all depends on what you mean. Tap water has more salt than purified water but purified water can hold more salt if salt is added. There is more room, so to speak, for the salt ions to fit into a container.
Because ammonium chloride can be removed from salt by sublimation (at a given temperature).
By sublimation
Rock salt (impure salt) is frequently colored.
Camphor is a volatile solid i.e. its vapour pressure becomes equal to the atmospheric pressure much below the melting point. But, common salt is non-volatile. Hence, camphor may be very easily separated from common salt by a physical process, SUBLIMATION! props to yahoo answers
