Can NaCl conduct electricity in solid state?
Solid sodium chloride does not conduct electricity, because there are no electrons which are free to move.
Is NaCl good conductor in solid state explain?
In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.
Why NaCl is not a conductor of electricity in solid state?
Sodium chloride is an ionic compound having sodium and chloride ions in its structure. Ionic compounds do not conduct electricity in solid state because ions are fixed in position and cannot move but in aqueous solution and in molten state they conduct electricity as ions are free to move.
Why sodium chloride is a poor conductor of electricity in solid state?
Solid [NaCl] is a bad conductor of electricity because the charged particles (ions) in solid [NaCl] are not capable of moving as they are bound by strong electrostatic forces. As a result, they can not conduct electricity.
Why is NaCl a good conductor?
As the motility of individual atoms or molecules in liquid state is far greater than solid, the ions (Na+&Cl−) are free to move and therefore can act as charge carriers. Hence molten sodium chloride is a good conductor of electricity because of free ions.
Is solid sodium a good conductor of electricity?
Solid sodium is good conductors of electricity as in sodium there is no band gap between the valence band and conduction band as they overlap with each other. The electrons are continuously available in the closed orbital which can conduct electricity. … Therefore, the ionic crystal of sodium chloride is an Insulator.
Is NaCl a good conductor of heat or electricity?
For the ‘conduction of electricity’, the element or compound must have free moving electrons or ions. NaCl is a “good conductor of electricity” in molten state but not is solid state.
Why does an aqueous solution of NaCl conduct electricity?
NaCl is an electrolyte. When in solution it dissociates into Na+ and Cl-. When you put electrodes in the solution, the cations are drawn to the cathode and the anions to the anode. This movement produces a current and that is why NaCl solutions can conduct electricity.
Why do ionic compounds not conduct electricity in solid state but conduct electricity in aqua state?
Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.
