Question

Why ionic compounds do not conduct electricity in solid state and why they conduct electricity in fused state

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.

hope that helps u..

Answer 2

Ionic bonds are attracted by strong force of attraction in solids....whereas in fused state there force of attraction is breaked where it conducts electricity....✌✌
