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.

Is NaCl a good conductor?

Sodium chloride is an electrolyte only in water solutions or when is melted. Solid sodium chloride is not a conductor of electricity.


Why is solid NaCl is a non conductor of electricity?

Na Cl in solid form is nonconductor because Na and Cl ions are strongly held by electrostatic forces but when dissolved in water or in molten state Na Cl is good conductor of electricity..

Why is NaCl and KI a conductor of electricity?

In dry or crystalline form, salt (Sodium Chloride) is a poor conductor. But when it is dissolved in water, the sodium forms Na+ ions and the Chlorine forms Cl- ions. With these extra ions in the water, it is easy for electrons to be carried through the solution and current to flow.


Is KCl a good electrical conductor?

yes KCl of potassium chloride is a good conductor of electricty, but ONLY when in an aqueous (water solution) or in molten (fused) state. It doesnot conduct in solid state.

Which substance meets the requirements cubic solid poor electrical conductor in the solid state good conductor when fused a sodium chloride b diamond c sulfur d chromium?

A, sodium chloride, because it is a crystalline solid. It has an ionic bond when in it's solid form and is a poor conductor. It is a good conductor of electricity in an aqueous state or when fused.
