Sodium metal as all metals are good conductor of electricity. Sodium has free delocalized electrons that can move, so electricity can pass through it. but sodium chloride is an ionic compound that has”t free electrons because it is solid at room temperature. ions are not free to move.
Why does sodium conduct electricity but sodium chloride does not?
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 is NaCl a good conductor of electricity?
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.
Did the sodium chloride NaCl conduct electricity?
For example, solid sodium chloride (NaCl, or table salt) does not conduct electricity; it is an insulator. If NaCl is placed into water, the mutual attraction both sodium (Na) and chlorine (Cl) have for water molecules cause their bonds to break (dissolving) and form ions (charged atoms or molecules) within the water.
Why does dry NaCl does not conduct electricity?
Solid NaCl or common salt does not conduct electricity because there are no free moving ions. However,when NaCl is dissolved in water, it breaks up into Positive sodium ions ( cations ) and negative chloride ions ( anions ).
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 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. So, sodium chloride does not conduct electricity in a solid-state. … So, the reason for the conductivity of sodium chloride in the molten state is the presence of free ions.
Why sodium chloride solution is a good conductor of electricity but does not have any effect on litmus solution?
So the solution is must be a solution of neutral electrolyte. For example NaCl is a neutral electrolyte which has no effect on litmus paper and the solution of NaCl conduct electricity as NaCl ionises to its constituent ions.
How can sodium chloride made to conduct electricity?
Sodium chloride is made of positively charged sodium ions and negatively charged choride ions. Ions carry electric charges and therefore through their motion they could conduct electricity. Therefore, NaCl can conduct electricity if its ions are free to move.
Which of the following is not a good conductor of electricity NaCl?
Solid $NaCl$- Solid $NaCl$ does not have free ions, nor does it have free electrons. So it cannot conduct electricity. Hence, option A is the correct choice.
Why do salt solutions conduct electricity?
Salt is sodium chloride. … 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.
