As a subject matter expert in the field of chemistry, I'd like to clarify a common misconception. Ionic compounds are actually quite good conductors of electricity, but under specific conditions. Let's delve into the reasons why.
Firstly, the conductivity of an ionic compound is highly dependent on its state. In the solid state, ionic compounds are typically poor conductors of electricity. This is because the ions are locked in a rigid lattice structure, and the lack of free-moving ions prevents the flow of electric charge. However, when an ionic compound is dissolved in water or melted, it becomes a good conductor of electricity.
When an ionic compound dissolves in water, the ions are separated from each other due to the polar nature of water molecules. Water, being a polar solvent, surrounds the ions, effectively solvating them and allowing them to move freely. This process is known as dissociation, and it is what enables the ions to carry an electric charge and conduct electricity.
In the molten state, similar principles apply. The heat energy provided melts the ionic lattice, allowing the ions to move freely. This mobility is what facilitates the flow of electric charge, making the molten ionic compound a good conductor.
Another important factor to consider is the strength of the ionic bonds. Ionic compounds with stronger ionic bonds will have a more stable lattice and thus be less likely to conduct electricity in the solid state. Conversely, compounds with weaker ionic bonds will have a less stable lattice and may conduct electricity more readily.
It's also worth noting that the size of the ions plays a role in conductivity. Smaller ions can pack more closely together, leading to a stronger lattice and potentially reducing conductivity. Larger ions, on the other hand, may result in a weaker lattice and increased conductivity.
Lastly, the type of ions present in the compound can also affect conductivity. Some ions are more mobile than others, and this mobility can significantly impact the compound's ability to conduct electricity.
In summary, while ionic compounds are not good conductors of electricity in their solid state due to the immobility of ions within the crystal lattice, they can become good conductors when dissolved in water or when molten, due to the mobility of the ions. The conductivity of ionic compounds is influenced by factors such as the strength of the ionic bonds, the size of the ions, and the type of ions present in the compound.

In summary, ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier" - it can be transferred without moving ions too far from their mean positions.Feb 25, 2016
