Why ionic substances do not conduct electricity as solid but when molten state?
Ionic substances do not conduct electricity as solids because the ions are locked in place and cannot move to carry the electric current. However, when the ionic substance is melted, the ions are free to move and carry the charge, allowing the substance to conduct electricity.
A substance that does not conduct electricity as a solid but does conduct electricity when melted is most likely classified as?
An ionic compound. Ionic compounds do not conduct electricity in their solid state because the ions are locked in place and cannot move to carry a charge. However, when melted, these ions are free to move and conduct electricity.
How can you determine experimentally whether or not a substance is present in ionic or molecular form when in aqueous solution?
One way is to measure the electrical conductivity. Ionic substances conduct electricity in solution, while molecular substances typically do not. Another method is to perform a precipitation reaction; when an ionic substance is mixed with a specific reagent, a solid precipitate forms if the substance is present. Lastly, you can use spectroscopic techniques like infrared spectroscopy to analyze the bonding patterns in the substance, since molecular and ionic compounds have distinct infrared spectra.
Does ionic compounds conduct in electricity?
Ionic compounds conduct electricity when they are dissolved in water or melted, allowing the ions to move and carry electric charge. Solid ionic compounds do not conduct electricity because the ions are fixed in place and unable to move to carry charge.
What generalizations can you make about a substance that is soluble in water and conducts electricity once it has dissolved?
The substance is ionic. In solid form it will not conduct as the ions are not free to move. If molten or in solution then the ions are free to move therefore they can complete a circuit and conduct electricty. E.g. salts, acids, alkalis.
If the substance dissolves in water but the solution does not conduct electricity is the substance an ionic compound?
No.

Does liquid naphthalene conduct electricity?
Naphthalene is a Ionic Substance. Hence, Ionic substance do not conduct when solid. But they do conduct when melted or dissolved in water - and they decompose at the same time. Therefor molten Naphthalene conduts electricity as the ions become free to move when dissolved in water.
When can ionic compound conduct electric?
An ionic compound can conduct electricity when it is in solution or melted.
Does ionic compounds conduct in electricity?

Do ionic compounds form solutions that conduct electricity well?
That's right, solutions of ionic compounds do conduct electricity well.

What type of substance can conduct electricity in the liquid but not solid phase?
Most ionic solids cannot conduct electricity in the solid phase. They only do so in the liquid phase. While they are solid, the ions in the ionic solid are fixed in their lattice so cannot move to conduct electricity whereas in the liquid phase, the ions are free and mobile and can act as charge carriers for electricity.
What type of compound ionic or covalent will conduct electricity and dissolve in water?
Ionic compounds generally dissolve in water dissociating to give ions that are free to move and conduct electricity. Molten ionic compounds also have free ions and conduct electricity. Ionic compounds generally do not conduct electricity in the solid form.
