What are the properties of ionic or Electrovalent compounds?
Answers
Answer:
1. Ionic Compounds are Hard Solids.
This is because their constituent particles are ions which are held by the strong electrostatic force of attraction and hence they cannot be separated easily.
2. Ionic Compounds Have A High Melting Point and High Boiling Point.
They are non-volatile solids. As in these compounds, ions are held by the strong electrostatic force of attraction, so a large amount of energy is required to overcome these forces of attraction between the ions.
3. Ionic Compounds Do Not Conduct Electricity in Their Solid-State.
However, they can conduct electricity in their fused, molten and in their aqueous solution. In solid-state, they do not conduct electricity as the ions are not free but held by the strong electrostatic force. But infused or molten state, these forces of attraction get weakened and thus the ions become free to conduct electricity. In aqueous solution, the high dielectric constant overcomes the strong electrostatic force of attraction, thus making the ions free to conduct electric current.
4. Ionic Compounds Act as Strong Electrolytes.
