The key subtopics in Solutions are: Types of solutions – solute & solvent, Expressing concentration – molarity, molality, mole fraction, Raoult's law – vapour pressure of solution, Ideal & non-ideal solutions, positive & negative deviations, Colligative properties – relative lowering of VP, Elevation of boiling point – Kb & molar mass, Depression of freezing point – Kf & molar mass, Osmosis & osmotic pressure – van't Hoff equation, Abnormal molar masses – association & dissociation, van't Hoff factor. Focus on these for CLASS 12 preparation.
Based on past paper analysis, Solutions typically has 1-2 questions in CLASS 12. Weightage: Medium.
Solutions questions are typically Numerical format. Expect calculation-based problems requiring formula application.
