FranIonic substances can conduct electricity because they contain charged particles called ions that are free to move. When an ionic substance dissolves in water or melts, the ions become mobile and are able to carry an electric charge, allowing the substance to conduct electricity.

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?
A substance that is soluble in water and conducts electricity once dissolved is likely an ionic compound. Ionic compounds dissociate into ions when dissolved in water, allowing them to conduct electricity. Common examples include salts like sodium chloride and potassium nitrate.
