PROPERTIES OF IONIC COMPOUND
- Physical nature: Ionic compounds are solids and 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.
- Melting and Boiling points: Ionic compounds have high melting and boiling points because a high amount of energy is required to break the strong inter-ionic attraction.
- Solubility: Electrovalent compounds are generally soluble in water and insoluble in solvents such as kerosene, petrol, etc.
- Conduction of Electricity: A solution of an ionic compound in water contains ions, which move to the opposite electrodes when electricity is passed through the solution.
- Hence they conduct electricity in the molten state.
- Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.
