The present book covers glimpse on basic formulae and concepts of adsorption and colligative properties of the solution along with solved Numericals. This would provide them a quick revision for different concepts in colligative properties of the solution like depression in freezing point, elevation in boiling point, osmotic pressure, degree of association and dissociation, concentration of solution in the terms of normality, molarity, and molality and so on. Also different concepts of adsorption like chemisorption, physisorption, factors affecting adsorption, Langmuir adsorption isotherm, Fruendlich adsorption isotherm are also covered.
