These are two phases (liquid and solid) of the same chemical compound, NaCl; molten salt is dissociated in ions.
I believe molten sodium chloride is simply solid NaCl heated to a liquid form, while brine is concentrated NaCl solute dissolved in water solvent, therefore the difference is the absence of water from molten sodium chloride. You may want to cross reference..
temperature and potential difference of electrodes.
Copper and molten sodium chloride are electrical conductors.
Molten sodium chloride consists of sodium ions and chloride ions and is therefore a conductor of electricity- and can be electrlysed.
In the molten state the ions of sodium chloride are free to move. Magnesium chloride would also conduct if it were molten. Since the ions of the magnesium chloride are bound together in the crystal lattice they cannot carry a current.
Molten rock is still a liquid. Igneous rock is what is formed when molten rock solidifies.
Sodium chloride is different from a metal as an electrical conductor. This is because sodium chloride is an ionic compound and therefore can only conduct electricity when molten or dissolved, as the ions are free to move in this state. However, metals can conduct electricity when solid or molten because the atoms are free to move in both states, therefore they can carry an electrical charge. This is therefore the difference between sodium chloride and metals as an electrical conductor.
Liquid sodium chloride would be salt in its molten state... in solution, salt is dissolved in another liquid, often water..
Sodium chloride is an electrolyte: - in water solution - as molten salt
By electrolysis of Molten Potassium chloride
Water solution of sodium chloride is an electrolyte; also molten sodium chloride.
In molten sodium chloride the free moving particles are Na+ and Cl- ions, during electrolysis sodium ion moves towards cathode and chloride ion towards anode.
