Naphthalene is a sublimate. A sublimate is a substance which changes directly from the solid state to the gaseous state and vice-versa. So, by utilising this property, we can separate the mixture of sodium chloride and naphthalene by heating it. The naphthalene will sublimate and we'll be left with sodium chloride.
Heating the mixture naphtalene become a gas after 218 0C and is released.
If you think to the decomposition of sodium chloride the method is the electrolysis of the molten NaCl.
Evaporation.
Evaporating hexane
NaCl itself will not render any hydrogen, however you can separate hydrogen from the water through the process of electrolysis. During electrolysis of NaCl solution, hydrogen will be evolved at cathode.
A solution of NaCl in a solvent in which the cations and anions separate, for example in water, can conduct electricity.
- evaporating water- distilling the solution
Sulfur is not soluble in water, sodium chloride yes. Filter the solution containing S and NaCl; sulfur remain on the filter, NaCl solution passes the filter. Evaporate te water by heating to obtain crystallized NaCl.
This process is called dissociation.
Sodium chloride is a solute when is dissolved in water (the solvent).
1. Put the mixture in water and stir. 2. AgCl is not soluble, NaCl is soluble. 3. After filtering NaCl passes in solution and AgCl remain on the filter.
117 grams of NaCl
Sodium and chlorine can be separated from NaCl by electrolisys.
Barium sulfate is insoluble in water; after filtration remain on the filter and sodium chloride pass as a solution.
Sodium chloride is a salt; the water solution is neutral.
NaCl is a compound known as the table salt.
