Concept:Ionic compounds conduct electricity in aqueous solution because they release free-moving ions.
Explanation:Ionic compounds are made of positively and negatively charged ions held in a lattice.
In the solid state, these ions cannot move, so no current flows.
When an ionic compound dissolves in water, the lattice breaks apart and the ions become free to move.
These mobile ions carry electric charge, so the solution conducts electricity.
Covalent compounds generally do not ionize readily in solution and they consist of molecules, not ions.
A hydrogen bond forms between hydrogen and a highly electronegative atom such as oxygen, nitrogen, or fluorine, not between a metal and a non-metal.
Therefore, the only correct statement is that ionic compounds in solution would conduct electricity.
Answer:D. Ionic compounds in solution would conduct electricity.
