Why solid NaCl Cannot conduct electricity but NaCl solution can?

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 is pure NaCl a non conductor of electricity but when dissolved in water a good conductor of electricity?

But when dissolved in water, the crystalline structure is broken down and the salt molecules become ions. The dipoles in the water separate the NaCl into Na+ cations and Cl− anions during solvation so the solution can conduct electricity.

Why sodium fluoride is able to conduct electricity when it is molten but not when it is solid?

Ionic bonding Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current . But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.

Is NaCl a good conductor of heat?

Ionic compounds such as sodium chloride (NaCl), on the other hand, readily dissolve in water and form ions (sodium and chloride, in this case) that can allow the solution to conduct heat (and electricity). Metals such as copper, silver, and aluminum are good conductors of heat. Hope this helps.

Will potassium chloride conduct electricity in solid state or in aqueous solution and why will it be soluble in water?

The melting process frees the ions in potassium chloride from their fixed positions in the crystal lattice. Since these ions can move freely under the influence of an electric field, they can conduct electricity. Solid ionic compounds o does not conduct electricity because the ions are held firmly in place.

Why is na a good electrical conductor?

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.

Why does Lici conduct electricity better than NaCl?

And as Li+ has less size compared to Na + it would have less resistance moving through solution. At their respective melting points, LiCI can conduct electricty better than NaCl. However, NaCl can conduct electricity better than LiCl in aqueous solution.

Does sodium chloride conduct electricity in its solid state?

Answer Wiki. For a substance to conduct electricity, it must have charge particles like electrons and ions within it that are able to move freely throughout it. In its solid state, sodium chloride (like many other ionic compounds) have fixed ions. This therefore means that the ions cannot move freely, a condition for the conduction of electricity.

What is the conductivity of Li+ and Na+ ions?

The conductivity depends upon the medium of these ions. In aqueous medium conductivity of Li+ ions is less than Na+ as due to hydration of Li+ ions many water molecules get attached with it making it heavier so less conductivity is observed, but in molten state of these ions conductivity of Li+ ions is more due to small size of it .

Why is electricity conducted in molten NaCl only?

This is because the hydration enthalpy ,i.e., the energy required per mole to dissolve the ions, is provided by the water to NaCl, so its ions got dissolved and can move freely and when connected to an EMF or Potential difference, they conduct electricity. So, in this way, electricity is conducted in molten/ aq NaCl only……
