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...

Exploring Crystalline Ionic Solids.

Crystalline solids have a regular internal arrangement of particles, a long range order, and sharp melting points. They are hard and rigid, with a characteristic heat of fusion. They are...

We've learned a lot about solution chemistry, and we've also learned about thermodynamics and spontaneity. So what about the spontaneity associated with dissolution? If an ionic solid dissolves in water, is this an enthalpically or...

Now that we have covered a variety of separation techniques, we know how to get an isolated product! But if it's a solid, it may contain impurities. Recrystallization is a common organic chemistry laboratory technique for the...

Learn the basics about Electrolysis of Molten Compounds. What is electrolysis? What are molten compounds? Find out more in this video!

We've learned a lot about covalent compounds, but we haven't talked quite as much about ionic compounds in their solid state. These will adopt a highly ordered and repeating lattice structure, but the geometry of the lattice depends...

Why do some things dissolve in water while others don't? Is a supersaturated solution just a beaker with a cape? All this and more!
