Why NaCl solution can be electrically conducting and solid NaCl are not?

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 Cannot solid NaCl conduct electricity but NaCl solution can?

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 can’t NaCl conduct electricity in solid state?

Solid sodium chloride does not conduct electricity, because there are no electrons which are free to move. When it melts, sodium chloride undergoes electrolysis, which involves conduction of electricity because of the movement and discharge of the ions. In the process, sodium and chlorine are produced.

Why is NaCl solid not an electrolyte?

Strong electrolytes completely ionize when dissolved, and no neutral molecules are formed in solution. Since NaCl is an ionic solid (s), which consists of cations Na+ and anions Cl−, no molecules of NaCl are present in NaCl solid or NaCl solution.

Is solid NaCl electrically conducting?

For example, solid sodium chloride (NaCl, or table salt) does not conduct electricity; it is an insulator. … Molten salts conduct electricity the same way they do when they are dissolved in water; some of the salt molecules are dissociated into ions, which allows the ions to conduct electricity.

Why NaCl solution is a good conductor of electricity?

When the sodium chloride dissolves in water, the sodium atoms and chlorine atoms separate under the influence of the water molecules. They’re free to move around in the water as positively and negatively charged ions. This separation of charge allows the solution to conduct electricity.

Why does NaCl conduct electricity when molten?

In an ionic compound, such as solid sodium chloride the free electrons are not present. Electrons are bound in bonds by strong electrostatic forces. … In a molten state, sodium chloride dissociates into a sodium ion and chloride ion and these ions conduct electricity.

Why ionic compounds in solid state do not conduct electricity but are able to do so in molten state?

Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move. … Hence, in the solid state, the ions are not free to move. While in molten form, these ions can freely move in the solution which also allows the passage of electricity.

Would solid NaCl conduct electricity Why did the salt make the water more conductive to electricity?

No, Solid NaCl (salt) do not have free electron to allow electric current to pass through the substances. In the presence of water and when a voltage is applied, it aids the salt to let the ions to be free, thus they are more in response to an electric field which makes NaCl to be able to conduct electricity.

Why does a block of NaCl not conduct electricity but it does when it is dissolved in water your answer submit clear form?

When solid NaCI cannot conduct electricity, it is because the positive and negative ions are locked in place and unable to move freely. When melted or dissolved in water, however, the crystal lattice breaks down and allows the charged particles to move freely. This, in turn, allows the conduction of electricity.

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

If you dissolve the crystal in a water (or melt it), the ions will be free to move, and so they would conduct electricity. In crystalline form, NaCl has no free ions. When dissolved in water, some NaCl dissociates into Na+ and Cl- ions, which is what allows for electrical conductivity.

Why does a substance not conduct electricity?

Ionic substances will not conduct electricity as solids. This is due to the fact that ions are not free to move in a solid as they are arranged in an ionic lattice. When an ionic substance is dissolved in solution or molten the ionic lattice is broken down allowing the ions to move freely and so conduction occurs.
