Surface and interfacial phenomenon: Electrical properties of interfaces and MCQs for GPAT, NIPER, Pharmacist and Drug Inspector exam

ELECTRICAL PROPERTIES OF INTERFACES: The existence of difference in electrical potential across a solid–liquid interface is demonstrated by the following phenomena: Electrophoresis: Movement of dispersed particles through a liquid medium under the influence of an electric field. Electro-osmosis: Movement of […]

Hydrophilic–Lipophilic Balance Concept, HLB classification and MCQs for GPAT, NIPER, Pharmacist and Drug Inspector exam

Hydrophilic–Lipophilic Balance Concept: The HLB concept was introduced by Griffin in 1947 to classify nonionic surfactants but has since been applied to ionic surfactants as well. In this system, each surfactant is assigned a number between 1 and 20, representing […]

Surfactants, Surface active agents and Question Answer for GPAT, NIPER, Pharmacist and Drug Inspector exam

SURFACE-ACTIVE AGENTS (SURFACTANTS): Substances having both hydrophilic and hydrophobic regions in their molecular structures are called surfactants or surface-active agents. When surfactants are added to the air/ liquid (water) interface, they accumulate at the interface, a process that is generally […]

Physical and chemical adsorption, Adsorption Isotherm, Adsorption phenomenon(Part1) and MCQs for GPAT, NIPER, Pharmacist and Drug Inspector exam

ADSORPTION PHENOMENA: Adsorption is the process in which materials of one phase (adsorbate) accumulate or concentrate at the interfacial surface of the other phase (adsorbent). It is a spontaneous phenomenon driven by a reduction of the surface free energy. Adsorption […]
