In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...

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...

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...

The Schottky defect and its consequences

Ionic crystals of type A B exhibit a Schottky defect, where an equal number of anions and cations are absent from lattice sites to maintain electrical neutrality. This defect is present...

The Born-Haber cycle calculates lattice energy using steps like ionization, electron affinity, and sublimation, showing the energetics of ionic compound formation

Lattice energy depends on ion size, charge, and the arrangement of ions in the crystal lattice. Smaller, highly charged ions increase lattice energy.

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

Calculating Thermochemical Radii from Born-Lande Equation

Born-Lande Equation: Sample Calculation

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...

We know that within an ionic compound, the ions are held together by ionic bonds. What is the strength of those bonds, and what is the lattice energy possessed by the entire lattice? Can we compare two compounds and say which has the...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

Determine Lattice Energy from Kapustinski Approximation

This nugget explains the general characteristics of compounds of alkali metals such as oxides, hydroxides, halides and salts of oxoacids.

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!

What the heck is dry ice and why is it so spooky? Learn this and more when we investigate phase changes and phase diagrams!
