Question

NaCl is a good conductor of electricity in molten state but not is solid state

Answer 1

Answer:

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

Explanation:

NaCl is good conductor of electricity in molten state bcoz Na furnish cation and Cl furnish anion

in molten state and they can move in this state so NaCl is good conductor of electricity in molten state but in solid state they are fixed and they cannot move due to lattice energy so NaCl is not good conductor in solid state
