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 the electrochemical gradient is a combination of the chemical and electrical gradient of ions. As ions move across a membrane the potential change creates a hidden force that isn't always apparent.

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...

SDS–PAGE is a widely used technique for qualitative analysis of protein mixtures, particularly during protein purification. Proteins are denatured using SDS and β-mercaptoethanol, which linearize the molecules and impart a uniform...

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

To break apart an ionic compound into its constituent ions.
