Applications of Adsorption

Science > Chemistry > Surface Chemistry > Applications of Adsorption In this article, we shall study some applications of adsorption. Adsorption Indicators: The phenomenon of adsorption is used to detect the endpoints of precipitation titrations. In such titrations, dyestuffs like eosin, fluorescein, alizarin red etc, are used as adsorption indicators. At the endpoint of the […]
