Suppose you want to test if a sample compound is ionic. You have these materials: the solid compound, a glass container, a spoon, and a conductivity apparatus. What material is missing from your list, and why is it necessary?


answer--an ionic compound is a substance that contains atoms that are bonded together through an ionic bond, where electrons are transferred from one atom to another. For the given experiment above, the material missing from the list is water or solvent. It is necessary because conduction through water will help you identify if a sample compound is ionic through its electrolytes. Ionic compounds that are soluble are typically electrolyte
