Question

Give scientific reason : Ionic compounds in fused state or in aqueous solution conduct electricity. (write atleast 4 sentences) .

Answer 1

Hi! 
An ionic bond is a chemical bond formed between two atoms (one atom which is a metal, and the other which is a non-metal) by transfer of electrons to attain an inert gas configuration. 

1. Ionic compounds are generally poor conductors of electricity when in the solid state beacuse the ions are held tightly due to the strong attraction and hence, they can't move about.

2. Electricity can flow when charged ions are available.

3. If you melt or dissolve an ionic compound in water, it readily dissociates due to which electrons can move freely, thus conducting electricity.

4. In fused state, a rise in the temperature leads to increase in the kinetic energy of the ions and so, the electrostatic forces are overcome. Since the ions can move, there is a flow of current.
