You have a non-conductive solid. On melting at 30^oC, it forms a conductive liquid. It is soluble in water, and when dissolved, the aqueous solution is conductive. Based on this information one can conclude that bonding in the solid is most likely

Question

Quizplus · Accepted Answer

The solid is likely ionic because its melting leads to a conductive liquid, indicating the formation of free ions that can carry charge. Additionally, its solubility in water and the resulting conductive solution suggest the presence of ions in solution, which is characteristic of ionic compounds.
