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.
To identify which one is ionic compound, you would select the compound with the high melting point. Ionic compounds have high melting points because the electrostatic interactions that hold the compounds together are very strong. Hope this answers the question.
The correct answer in the blank is highest melting point.
