Precipitation Reactions: Crash Course Chemistry
A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this...

Ionic Solids
In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of ionic...

Solutions
In this video Paul Andersen explains the important properties of solutions. A solution can be either a solid, liquid or gas but it must be homogeneous in nature. The solutes can not be separated with a filter and so either chromatography...
