Gibbs adsorption isotherm

The Gibbs adsorption isotherm describes how molecules accumulate at the surface of a liquid or solid in contact with a gas or another liquid. It helps us understand the relationship between the concentration of these molecules in the bulk phase and their concentration at the surface. Essentially, it shows that as the concentration of a substance increases in the bulk (like a dissolved gas), more of that substance will settle at the surface. This is important in fields like chemistry and materials science, as it influences surface properties and behaviors in various applications, such as detergents and coatings.
