Important Points to Remember – Class 12 Chemistry

• Solutions are homogeneous mixtures where composition and properties remain uniform throughout, forming the foundation of Chapter 1 in NCERT Chemistry Part I.
• Henry’s law states that the solubility of a gas in liquid is directly proportional to the pressure of gas above the solution at constant temperature.
• Raoult’s law applies to ideal solutions where partial vapor pressure of each component equals the product of its mole fraction and vapor pressure in pure state.
• Colligative properties (osmotic pressure, boiling point elevation, freezing point depression, vapor pressure lowering) depend only on number of solute particles, not their nature.
• Electrochemistry deals with conversion of chemical energy to electrical energy (galvanic cells) and electrical energy to chemical energy (electrolytic cells).
• Nernst equation: E = E° – (RT/nF) ln Q, used to calculate EMF of galvanic cells under non-standard conditions in CBSE 2024-25 syllabus.
• Standard electrode potential (E°) is measured under standard conditions: 1M concentration, 1 bar pressure, 298K temperature.
• Kohlrausch’s law states that molar conductivity at infinite dilution is sum of individual contributions of cations and anions.
• Chemical kinetics studies rate of reactions and factors affecting reaction speed, including concentration, temperature, and catalysts.
• Rate constant (k) is specific for each reaction at given temperature and remains independent of concentration of reactants.
• Order of reaction is sum of powers of concentration terms in rate law, while molecularity is number of molecules participating in elementary reaction.
• Transition metals (d-block elements) have partially filled d-orbitals in ground state or common oxidation states as per IUPAC definition.
• Inner transition metals include lanthanoids (4f series: Ce to Lu) and actinoids (5f series: Th to Lr) with partially filled f-orbitals.
• d-block elements show variable oxidation states, colored compounds, catalytic properties, and complex formation due to unpaired d-electrons.
• Coordination compounds formation is characteristic property of transition metals due to availability of vacant d-orbitals for bonding.

Quick Revision Notes – Class 12 Chemistry

• Memory tip for Raoult’s law deviations: Positive deviation (P > P°) occurs when A-B interactions are weaker than A-A or B-B interactions; negative deviation shows opposite behavior.
• For CBSE board exams 2025-26, focus on numerical problems of molarity, molality, mole fraction, and ppm – these carry 2-3 marks consistently.
• Electrochemical series arrangement: Higher the reduction potential, greater the tendency to get reduced; Zn/Zn²⁺ (-0.76V) to Au³⁺/Au (+1.40V).
• Quick formula for conductivity problems: κ = G × (l/A) where κ is conductivity, G is conductance, l is length, A is area of cross-section.
• Rate law can only be determined experimentally, never from balanced chemical equation – important concept for 3-mark questions in boards.
• Integrated rate equations to memorize: Zero order: [A] = [A₀] – kt; First order: ln[A] = ln[A₀] – kt; Second order: 1/[A] = 1/[A₀] + kt.
• Arrhenius equation k = Ae^(-Ea/RT) shows exponential dependence of rate constant on temperature – often asked in 5-mark derivation questions.
• Electronic configuration pattern for d-block: [Noble gas] (n-1)d¹⁻¹⁰ ns¹⁻²; exceptions include Cr ([Ar] 3d⁵ 4s¹) and Cu ([Ar] 3d¹⁰ 4s¹).
• Lanthanoid contraction causes decrease in atomic radii from La to Lu due to poor shielding effect of f-electrons, affecting properties of 5d series.
• Color in transition metal compounds arises from d-d electronic transitions when unpaired electrons absorb visible light energy.
• Diagram focus areas: Galvanic cell setup with salt bridge, electrolytic cell for metal extraction, and crystal field splitting in coordination compounds.
• Important industrial processes: Chlor-alkali process (NaCl electrolysis), extraction of aluminum (Hall-Heroult process), electroplating applications.
• Catalyst mechanisms: Homogeneous catalysts form intermediate compounds; heterogeneous catalysts provide surface for reaction with lower activation energy.
• Marking scheme tip: Always write units in numerical answers, show all steps in derivations, and draw neat labeled diagrams for full marks.
• Last-minute revision focus: Practice previous year questions from chapters on Solutions, Electrochemistry, Chemical Kinetics, and d-f block elements for guaranteed scoring.
