Why does sodium chloride conduct electricity when molten but not solid?

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 sodium chloride only conduct electricity when liquid?

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 solid sodium chloride not conduct electricity but molten does?

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.

What conducts electricity when molten but not solid state?

Ionic solids conduct electricity in molten state but not in solid state.

Why is sodium oxide a non conductor of electricity?

(a) Explain why solid sodium oxide is a non-conductor of electricity. 1. The ions are bound tightly to a crystal kebice and are not free to move.

Why does liquid iodine does not conduct electricity?

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

Why can molten sodium fluoride conduct electricity?

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. However, when it is in its molten state, the ions are free to move around, thus making them free to conduct electricity.

Why do molten metals conduct electricity?

Ans:Conduction in molten metal is due to electrons. Reason:Flow of electricity in metals is due to the flow of electrons only,i.e.,there is no flow of matter. Conductance in metals depends upon the structure,density of metal and the no of valence electrons per atom.

Why do ionic compounds not conduct electricity in solid state but they do so in molten state Class 10?

This is because, in ionic compounds, electricity is conducted by ions. In contrast, ions are held together by strong electrostatic forces in a solid-state and are not free to move about within the solid. Hence, in molten state or solution form, the ions are free to move and conduct electricity.

Can sodium chloride conduct electricity in the solid state?

NaCl does not conduct electricity in solid state whereas it does conduct electricity in aqueous solution as well as in molten state.

Why is sodium chloride 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.

Why does molten salt conduct electricity but molten dioxide doesn t?

What you can safely say is that because the metallic oxides and silicon dioxide have giant structures, the melting and boiling points are all high. Silicon dioxide doesn’t have any mobile electrons or ions – so it doesn’t conduct electricity either as a solid or a liquid.

Is molten sodium chloride 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.
