A solution of sodium chloride conducts electricity but solid sodium chloride is a bad conductor of electricity
Answers
We know that the Sodium chloride is the Ionic Compound, thus being an ionic compound it posses many properties similar to Ionic compound.
As a result, Being an Ionic solid, it has the ions which are held together by very large force of the attraction between the lattice of the solid. Due to the binding force, the ions are not free and hence they are non-conduction when in the solid state.
Now, But when the Sodium chloride is dissolved in water, Water being an polar compound ionizes and breaks the force of the attraction of the ions in Ionic solid and hence the Solution of the sodium chloride becomes conducting.
Hence, As solution or also in the molten state sodium chloride becomes conduction due to the free mobile ions but remains nonconducting in solid state due to immobile ions.
Hope it helps.
