Because ions (Na+ and Cl-) cannot move in their crystallic (= solid) lattice. When dissolved in water they can freely move around seperately: Na+ moves to the cathode (- , negative electrode) Cl- move to the + side anode.
The scope is to obtain pure sodium and chlorine.
Solid NaCl is not an electrolyte; the saline solution or the molten NaCl are electrolytes.
for the conductance of electricity freely moving ions and electrons are necessary. But in NaCl (in solid form) Na positive ion and Cl negative ion are held together by strong electrostatic force and there is no freely moving ion in NaCl (in solid state) therefore NaCl does not conduct electricity in solid form.
Solid sodium chloride is not an electrolyte. Water solutions of sodium chloride or molten NaCl are electrolytes.
Solid sodium chloride is not an electrolyte; water solution of NaCl is an electrolyte (also melted NaCl).
The solid copper is a conductor but not an electrolyte.
1. Water solution of sodium chloride is an electrolyte containing ions as Na+ and Cl-. 2. Solid sodium chloride is not an electrolyte. 3. Also sugar is not an electrolyte.
Because in solid state NaCl is neutral, without free ions or electrons.
Solid sodium chloride is not conductive; the water solution of NaCl (or wet NaCl) being an electrolyte is conductive.
Yes, NaCl is an electrolyte.
In water sodium chloride is dissociated and the solution become an electrolyte, electrically conductive. The solid NaCl is not an electrolyte.
Sodium chloride is an electrolyte only in water solutions or when is melted. Solid sodium chloride is not a conductor of electricity.
