Question

solid sodium chloride does not conduct electricity while sodium chloride solution conduct give reason

Answer 1

In order to conduct electricity a substance must have charge particles, such as electrons and ions, that are free to move freely through it. 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.

Answer 2

We have three types of bonds :

1.) Bonds between metals - Metallic bonds.

2.) Bonds between non metals - Covalent bonds

3.) Bonds between metals and non metals - Ionic bonds

Metallic bonds form structures which conduct electricity in both liquid and solid state.

This is because they have electrons that are mobile within their structures.

Ionic bonds form structures which conduct electricity only in liquid state that is in solution form.
