What property of sodium chloride is used to separate it from the sand?
Solubility :Based On solubility ,sodium chloride is separated . Sodium chloride is soluble in water but sand is not soluble .
Melting Point : Melting of Salt is not easy due to presence of high electrostatic force or ionic force. it requires very high temperature .For NaCl melting point =801℃ and sand does not melt at normal Condition.Hence on Basis of m.p separation does not take place in normal condition.
Oxidation : On oxidation of sodium chloride Changes .That means sodium chloride lost its identity .Hence separation does not take place
Chemical reaction with the Sand: sodium chloride does not react with sand in solution .But in a mixture ,separation does not take place by this property.
