Properties of ionic compounds. |
|
Answer» Properties of ionic compounds (a) Non-directional nature of ionic bond : These compounds do not exist as individual molecules. Instead they are often hard solids, always made up of ions held together by strong electrostatic forces of attraction between ions with opposite charge. (b) Electrical conductivity : When put into water, the ions fall apart. The solution can thus conduct electricity. Similarly, these compounds conduct electricity in the fused state also. (c) Melting and boiling points : These compounds generally have high melting points. This is because a lot of thermal energy is required to break down the inter-ionic forces and form a liquid. Similarly, they possess high boiling points. (d) Solubility : These compounds are usually soluble in water but insoluble in benzene or other organic solvents. |
