Answer 1

Binding of a molecule or a particleon the surface of another substance is adsorption. Absorption on the other hand is the diffusion of a molecule throughout the bulk of a solid or liquid. Dissolution of any solute into a solvent is absorption and Activated charcoal is used to adsorb toxic molecules from waste water, which is an example of adsorption.
