Ionic Solids - Chemistry

This chemistry video covers a tutorial on ionic solids. It explains how the lattice structure of ionic solids and the Coulomb interactions between the ions are used to describe their properties including low vapour pressure, high boiling and melting points, brittleness and poor conductivity in the solid phase. The cations and anions in ionic solids are arranged to minimise repulsion between opposite charges. In the liquid state, the ions are mobile and conduct electricity.
