प्रश्न
Explain why, ionic compounds conduct electricity in solution whereas covalent compounds do not conduct electricity.
उत्तर
An ionic compound consists of ions held by strong forces in solid state. But when an ionic compound dissolves in water to form a solution, the constituent ions get separated and they disperse across the solution. This helps in conducting an electric current through the solution. Covalent compounds are formed by the sharing of electrons. So ions that conduct electricity are not involved in these compounds. Hence covalent compounds do not conduct electricity.
