Ionic compounds only have high conductivity in a molten state. Because they are composed largely of a tightly-bonded lattice of cations and anions, electric charge cannot flow through the lattice because of the lack of freedom possessed by any negatively charged particles.
When the compound is in a liquid state, the electrostatic bonds between the cations and anions are weakened, allowing the negatively charged ions to move freely and, because of this, it easily conducts a charge.
Hope that's been some use :)

What is the electrical conductivity of ionic compounds?
Ionic compounds typically have low electrical conductivity in the solid state because the ions are tightly held in a fixed lattice structure. However, when ionic compounds are melted or dissolved in water, the ions are free to move and conduct electricity.
Do Ionic compounds have poor or good conductivity?
Ionic compounds have good conductivity when in solution or molten state because the ions are free to move and carry an electric charge. However, in solid form, ionic compounds have poor conductivity because the ions are held in fixed positions and cannot move to carry a charge.
Do ionic compounds have poor electrical conductivity in the solid state?
Yes, ionic compounds have poor electrical conductivity in the solid state because the ions are fixed in position and cannot move to carry electric charge. However, they can conduct electricity when melted or dissolved in water, allowing the ions to move freely.
What are the difference in conductivity between ionic and molecular compounds?
Ionic compounds typically have higher conductivity than molecular compounds because ionic compounds dissociate into ions in solution, allowing for the flow of electric current. Molecular compounds, on the other hand, do not dissociate into ions in solution and therefore exhibit lower conductivity.
Do Orderly crystal shapes high melting points and electrical conductivity when dissolved in water are properties of ionic compounds?
Yes, orderly crystal shapes, high melting points, and electrical conductivity when dissolved in water are properties of ionic compounds. Ionic compounds consist of positively and negatively charged ions that form strong bonds, leading to their high melting points and orderly crystal structures. When dissolved in water, ionic compounds dissociate into ions that can conduct electricity.
What is the electrical conductivity of ionic compounds?

How does the electrical conductivity of ionic compounds change when they are melted or dissolve in water?
Melting or dissolving ionic compounds increases the electrical conductivity. This is because there are free mobile charged ions that can move in the electric field and conduct current.

Do Ionic compounds have poor or good conductivity?
Ionic compounds have good conductivity when in solution or molten state because the ions are free to move and carry an electric charge. However, in solid form, ionic compounds have poor conductivity because the ions are held in fixed positions and cannot move to carry a charge.
Is ionic compounds electrical conductivity in liquid state poor or good?
There are free ions in the liquid state of ionic compound, hence the are good conductors of electricity.
Do ionic compounds have poor electrical conductivity in the solid state?
Yes, ionic compounds have poor electrical conductivity in the solid state because the ions are fixed in position and cannot move to carry electric charge. However, they can conduct electricity when melted or dissolved in water, allowing the ions to move freely.

Why does the electrical conductivity of ionic compounds change when they are melted or dissolved in water?
The electrical conductivity of ionic compounds increases when they are melted or dissolved in water because the ions are free to move and carry electric charge. In the solid state, the ions are fixed in place and cannot conduct electricity. When melted or dissolved, the ions are able to move freely and carry electric current.
Ionic compounds often have higher melting point than metals. Using at least 2 properties of ionic compounds explain why is cookware not made from ionic compounds?
Cookware needs to have good thermal conductivity, while ionic compounds have poor conductivity. Additionally, ionic compounds are brittle and prone to shattering when subjected to mechanical stress, making them unsuitable for cookware that requires durability and resistance to impact.
Is ionic compound electrical conductivity in the liquid state good or poor?
Ionic compounds have good electrical conductivity in the liquid state because the ions are free to move and carry an electric charge. In the liquid state, the ions are not held in fixed positions like in the solid state, allowing them to flow and conduct electricity.
How does the elctrical conductivity of ionic compounds change when theey are melted or dissolved in water Why is this so?
Electrical conductivity rises dramatically, and this is due to mobile ions that move in solution or the molten salt under the influence of an electrical field. These mobile ions carry the current.
