Properties of ionic compound
- PHYSICAL NATURE :- They are solid and hard (because of the strong force of attraction between the positive and negative ions) . They are brittle.
- Melting and boiling point:_ They have high melting and boiling pont.
- Solubility :- soluble in water and insoluble in solvents such as kerosene , petrol etc.
- Conductor of electricity :- Ionic compound conduct electricity in molter (ions move to the opposite electrodes when electricity is passed )
- They do not conduct electricity in solid state as movements of ions is not possible in solid They conduct electricity in molten state.
