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...

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...

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...

In this video Paul Andersen explains how intermolecular forces differ from intramolecular forces. He then explains how differences in these forces account for different properties in solid, liquids and gases. Some of these properties...

Discover the truth about lattice energy and why size really matters in ionic bonds. In this video, you'll learn what lattice energy is, why it's crucial in chemistry, and the factors that influence its strength. Understand how the size...

In this video we are going to look how to name binary ionic compounds. These compounds deal with the ionic bonding of 2 different elements. Remember that an ionic compound is formed between a metal and a nonmetal or a cation and an...

In this video, I'm going to show you a simple way to identify the type of chemical reaction that is happening in a given situation. This will help you to understand the process more easily and to carry out the reaction in a more accurate...

Lattice energy is the energy released when ions combine to form an ionic solid. Higher lattice energy indicates a stronger ionic bond and greater stability

Fajan's rules explain how factors like ion size, charge, and polarizability determine whether a bond will be predominantly ionic or covalent

Cations, formed by electron loss, influence ionic bond strength. Smaller cations with higher charges create stronger ionic interactions

To break apart an ionic compound into its constituent ions.
