ii.4. Properties of Ionic Compounds
Physical Nature of Ionic Compounds: Exploring the Solid State, Hardness, Melting Points and Electrical Conductivity of Electrovalent Compounds
State of Matter and Hardness
|
- 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.
|
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 and insoluble in solvents such as kerosene, petrol, etc.
|
Conductivity of Electricity
|
- The conductivity 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.

Understanding these properties Of metals and its Conductivity provides insights into the diverse behaviors of ionic compounds, influencing their applications across various scientific and industrial domains.
