Best answer: Why does solid NaCl not conduct electricity whereas in the molten state it conducts electricity?

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 solid NaCl not conduct electric current but molten NaCl?

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 sodium chloride does not conduct electricity as a solid yet when melted it does conduct electricity?

Solid ionic compounds do not conduct electricity because the ions are held firmly in place. … But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity. When a crystal of an ionic compound dissolves in water, the ions separate.

Why is NaCl a solid state insulator?

The Solid state of NaCl does not have free electrons and hence it does not contain electricity. … Thus these ions help to conduct electricity.

Can solid NaCl conduct electricity?

Solid sodium chloride does not conduct electricity, because there are no electrons which are free to move.

Is NaCl a good conductor of electricity?

The solution of sodium chloride in water is a good conductor of electricity because of the ions that act as the charge carriers.

Can C6H12O6 conduct electricity?

Copper conducts electricity, while sugar, C6H12O6, does not.

Do all salts conduct electricity?

Explanation: Salts are ionic compounds. Ionic compounds cannot conduct electricity when solid because, although they are entirely composed of charged particles called ions, these ions are not free to move: a factor vital to conduction of electricity. This static inertia is not maintained when the compound is melted.

Does fluoride conduct electricity?

Fluorine, like other non-metals (except graphite and silicon) does not conduct electricity. It is the most electronegative atom and is very reactive because of which it only gains electrons and does not lose them.

Is NaCl a insulator?

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.

Is NaCl a diamagnetic solid?

NaCl is an example for diamagnetic substance. In case of ferri magnetic substances net magnetic moment is not zero. …

Is Fe a insulator?

It is an excellent conductor of electricity. Electrical wires are made up of copper only. – Iron is also a metal. … It doesn’t conduct electricity and therefore, it is an insulator.

Why NaCl has high melting and boiling point?

Sodium chloride has a high melting point and boiling point because of the strong electrostatic attraction between its positive and negative ions. This requires more heat energy to overcome the force of attraction.

Does a diamond conduct electricity?

Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. … It does not conduct electricity as there are no delocalised electrons in the structure.

Is melted sugar an electrical conductor?

No, sugar solution does not conduct electricity. … Sugar molecules are held by covalent bonds, as a result, they do not dissociate free ions in water. Unlike electrolytic solution, sugar solution does not dissociate free ions making it an insulator.
