Why electrical conductivity is a suitable test for ionic compounds?

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?
better than the electrical conductivity of molecular compounds
Do ionic compounds have poor electrical conductivity in the solid state?
poor
Do Ionic compounds have poor or good conductivity?
Ionic Compounds have poor conductivity when it is solid. Ionic Compounds have great conductivity when it is either dissolved in water or is melted
Are orderly crystal shapes high melting points and electrical conductivity when dissolved in water properties of ionic compounds?
yes it is ionic
What properties may be used to ionic compounds?
crystal shape, high melting points, and electrical conductivity
What is the electrical conductivity of ionic compounds?
better than the electrical conductivity of molecular compounds
Do ionic compounds have poor electrical conductivity in the solid state?
poor
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.

What properties may be used to identify ionic compounds?
crystal shape, high melting points, and electrical conductivity
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 Orderly crystal shapes high melting points and electrical conductivity when dissolved in water are properties of ionic compounds?
Yes this is true.
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.
When can ionic compounds conduct electricity when can't they?
Generally when they are solids. There are ionic compounds called fast ion conductors that do dispaly conductivity in the solid but these are extremely rare)
