Filtration because it says that it can separate fine solid from liquids.
Boil the water so that the salt can recrystallize thus separating the salt from water (evaporation).
No, it is a physical process.
It is called filtration.
Gas Chromatography is an excellent technique for measuring naphthalene in water.
Naphthalene is said to be somewhat soluble in ethyl alcohol (ethanol). It is insoluble in water and very soluble in ether, chloroform, or carbon disulfide.
no
The process is called sublimation.
Sublimation
by sublimation
dissociation
Evaporation, boiling or distillation will all result in separating the salt from the water.
The reason why naphthalene can be dissolve in ether and not in water is because of their polarity. Naphthalene is a non-polar molecule. so it can only dissolve with a non-polar molecule.
