Quick Answer: Why does sodium chloride conduct electricity in the liquid state?

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 sodium chloride only conduct electricity when liquid?

Free atoms do not conduct electricity because they are not charged. So, the reason for the conductivity of sodium chloride in the molten state is the presence of free ions.

Why does sodium conduct electricity as a liquid?

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.

Does sodium chloride conduct electricity in solid and liquid state?

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 sodium chloride 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.

Why does liquid iodine does not conduct electricity?

Iodine does not conduct electricity since each molecule of iodine comprises twoiodine atoms joined by a covalent bond that cannot be excited sufficiently to transfer electrical energy.

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.

Does sodium conduct electricity in its solid state?

In solid state ions are fixed and cannot move and therefore sodium chloride cannot conduct electricity in solid state but produces it in aqueous and molten state.

What is the electrical conductivity of sodium chloride?

Quist and Marshall [1968] measured the electrical conductivity of NaCl-H2O fluid at 0.001–0.1 mol/kg (0.58 wt % NaCl), 0.1 MPa–0.4 GPa, and 373–1073 K.

Why do solid and liquid metals conduct electricity?

In a metal, the valence electrons are loosely held. They leave their “own” metal atoms, forming a “sea” of electrons surrounding the metal cations in the solid. The electrons are free to move throughout this electron sea. … Thus, metals are good conductors 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 thesubstances. In the presence of water and when a voltage is applied, it aids the salt to let theions to be free, thus they are more in response to an electric field which makes NaCl to beable to conduct electricity.
