why can't common salt dissolve in alcohol?

Question

is it any related to the arrangement of particles in alcohol?

Answer 1

It does dissolve, just at a lower level. The polar nature of salt requires a polar solvent to get into solution, and alcohol doesn't have much ability to stabilize the charge. It is more soluble in methanol than higher molecular weight alcohols.

You want to make use of the difference in solubility of caffeine vs. sodium chloride in various solvents. Caffeine is only slightly soluble in water while salt is highly soluble in water. The opposite is true for organic solvents (though I don't know what you mean by "propanons"). The key is to find an organic solvent that is not water miscible, for example trichloroethane (TCE) or chloroform. Then add your caffeine-salt mixture to a water-TCE mixture. The salt will dissolve in the water, the caffeine in the TCE. Put these in a separatory funnel, shake the hell out of it, and draw off the water layer. Dry the TCE layer (over a drying agent) and evaporate off the solvent. You'll have relatively pure caffeine. If you save the water layer, you can extract any of the caffeine that dissolved in it by another TCE extraction.

Answer 5

Alcohol is a nonpolar solvent. Common salt will not dissociate in alcohol.
The process of dissolving, called dissolution, is relatively straightforward for covalent substances such as ethanol. When ethanol dissolves in water, the ethanol molecules remain intact but form new hydrogen bonds with the water. When, however, an ionic compounds such as sodium chloride (NaCl) dissolves in water, the sodium chloride lattice dissociates into separate ions which are solvated (wrapped) with a coating of water molecules. Nonetheless, NaCl is said to dissolve in water, because evaporation of the solvent returns crystalline NaCl.
The solubility of one substance dissolving in another is determined by the balance of intermolecular forces between the solvent and solute and the entropy change that accompanies the solvation. Factors such as temperature and pressure will alter this balance, thus changing the solubility. Solubility may also strongly depend on the presence of other species dissolved in the solvent, for example, complex (chemistry) forming anions (ligands) in liquids. Solubility will also depend on the excess (or deficiency) of a common ion (common-ion effect). To a lesser extent, solubility will depend on the ionic strength of liquid solutions.

Answer 6

The reason for the poor dissolving is because the polarity of the alcohol is not strong enough to overcome the salt's ionic attraction.
