Question

Ionic compounds do not conduct electricity in a molten state but will conduct in a free state? Explain why?

Answer 1

Ionic compounds are composed of two elements. The ionic bond between these two elements is strong. In solid state there is no availability of free electrons and also there is no probability for the formation of ions. So ionic compounds do not conduct electricity when they are solid, but they do conduct electricity when they are dissolved in water or when they are melted because in molten state these ionic compounds forms ions. these ions are responsible for the conduction of electricity.

Answer 2

Explanation: In molten state or dissolved state ionic compounds conduct electricity because they contain charged particles called cations and anions. These ions are free to move to conduct electricity. But in solid state they do not conduct electricity as there is no free cation or Anion available.
