Chapter 17

List the properties of a substance that would definitely establish that the material is ionic.

A given substance is a white solid at \(25^{\circ} \mathrm{C}\). It melts at \(80^{\circ} \mathrm{C}\) without decomposing, and the melt has a small electrical conductivity. What would be the classification of the substance, based on this information?

A white solid melts at \(1000^{\circ} \mathrm{C}\). The melt does not conduct electricity. Classify the substance as best you can from these properties.
