Physical nature:
Ionic compounds are solids and are somewhat hard because of the strong force of attraction between the positive and negative ions.
These compounds are generally brittle and break into pieces when pressure is applied.

7
Melting and Boiling points:
Ionic compounds have high melting and boiling points
This is because a considerable amount of energy is required to break the strong inter-ionic attraction.

Solubility
Electrovalent compounds are generally soluble in water
Insoluble in solvents such as kerosene, petrol, etc.

Conduction of Electricity
The conduction of electricity through a solution involves the movement of charged particles.
A solution of an ionic compound in water contains ions, which move to the opposite electrodes when electricity is passed through the solution.

Ionic compounds in the solid state do not conduct electricity because the movement of ions in the solid is not possible due to their rigid structure.
15
Ionic compounds conduct
electricity in the molten state.
This is possible in the molten state
since the electrostatic forces of attraction between the oppositely charged ions are overcome due to the heat. Thus, the ions move freely and conduct electricity.
