Why when solid sodium chloride dissolves in water does it dissociate to form a strong electrolyte?

Why is it a strong electrolyte? Because the ions in the solution are free to move around and can move towards electrodes. Why does it dissociate? Because the free energy of the system becomes less. Free energy is the combined effect of enthalpy change and entropy change. The ions are surrounded by oppositely charged ions in the crystal, and by polar water molecules in the solution. This change requires a small energy input, but this is more than outweighed by the large increase in entropy as the ions spread out and mix up with the water.

Is dry sodium chloride a strong electrolyte?
Solid sodium chloride is not an electrolyte.
What happens if distilled water gets added to sodium chloride?
It will burst out the soda crystals and distilled water.
Solid sodium chloride does not conduct electricity but in molten state conduts electricity readily.Why?
Melted sodium chloride is an electrolyte containing the cation Na+and the anion Cl-.
Why does sodium chloride is a strong electrolyte?
Sodium chloride is an electrolyte only in solution or as melted, when is completely dissociated in ions.
Why is sodium chloride not a conductor?
Because solid sodium chloride is not an electrolyte.
Is sodium chloride an elecrtolyte?
Sodium chloride is an electrolyte in solution or when is melted.
Is sodium chloride eletrolyte?
Water solution of sodium chloride is an electrolyte; also molten sodium chloride.
Why does a mixture of sodium chloride and water conduct electricity but sodium chloride crystal does not?
Sodium chloride solution is an electrolyte containg ions as Na+ and Cl-. Sodium solid crystal is not an electrolyte, is not dissociated.
Why does sodium chloride and water conduct electricity but a sodium chloride crystal does not?
In water sodium chloride is dissociated and the solution become an electrolyte, electrically conductive. The solid NaCl is not an electrolyte.
Why does aqueous sodium chloride conduct electricity but dry sodium chloride does not?
Because sodium chloride solution is an electrolyte, containing ions Na+ and Cl-. Solid NaCl is not an electrolyte.
Is sodium chloride an elctrolyte?
Sodium chloride is an electrolyte when it is in water solution or when is melted.
Is sodium chloride a nonelectrolyte?
Sodium chloride is an electrolyte when is in a water solution or melted.
