Adsorption

Science / Chemistry / Adsorption: Adsorption is collection of a substance on the surface of a solid or a liquid. For example, gases that make water taste bad are strongly adsorbed on charcoal granules in water filters.

Adsorption Indicator

Science / Chemistry / Adsorption Indicator: A substance that indicates an excess of a reactant in a precipitation reaction. For example, dichlorofluorescein is added to an NaCl solution being titrated with silver nitrate. Before the endpoint, e MORE

Adsorption Chromatography

Science / Chemistry / Adsorption Chromatography: A technique for separating or analyzing mixtures that contain at least one component that is preferentially adsorbed by the stationary phase as it moves over it. MORE
