User: You are given the melting points of three unknown substances and are asked to predict which one is an ionic compound. You would select the compound with the melting point.
Weegy: You would select the compound with the greatest melting point. Ionic compounds have very strong mutual bonds and thus are very difficult to change from solid to liquid state. [ Thus, they require high energy in the form of heat to get converted to liquid state. So ionic compounds have high melting points. ] (More)
