IB Chemistry SL study plan

IB Chemistry SL · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Structure 1 - Models of the particulate nature of matter & Experimental programme and skills in the study of chemistry (including the internal assessment investigation)

  • Convert between number of particles, amount in mol, mass and molar mass using Avogadro's constant in multi-step problems.

  • Solve for any variable in pV = nRT, including cases where molar mass or gas density must be derived, and cases where a gas is collected over water.

  • Use the assumptions of the kinetic molecular theory to explain why a real gas deviates most from ideal behaviour at high pressure and low temperature.

  • Write full and condensed electron configurations for atoms and ions up to Z = 36, including the 4s/3d filling order and the chromium and copper anomalies.

  • Record raw measurements with correct significant figures and absolute uncertainty, and propagate uncertainty through addition and multiplication.

Your checkpoint

A timed 30-item S1 plus measurement set, scored and fully corrected, with a written error log naming each misconception in one sentence.

Week 2

Reactivity 2 - How much, how fast and how far? & Structure 1 - Models of the particulate nature of matter

  • Balance molecular and ionic equations and identify the limiting reactant when two solutions of known concentration are mixed.

  • Calculate theoretical yield, percentage yield and atom economy for a named synthesis, and explain the gap between them.

  • Perform titration calculations from concentration, volume and mole ratio data, including dilution steps.

  • Convert a calculated amount in mol into a gas volume at a stated temperature and pressure using the ideal gas equation.

Your checkpoint

Three multi-part exam-style stoichiometry questions completed in 60 minutes under timed conditions, self-marked against the mark scheme with every lost mark re-attempted in writing.

Week 3

Reactivity 2 - How much, how fast and how far? & Experimental programme and skills in the study of chemistry (including the internal assessment investigation)

  • Explain the effect of concentration, pressure, surface area, temperature and a catalyst on reaction rate using collision theory.

  • Interpret Maxwell-Boltzmann distribution curves to explain how temperature and a catalyst change the proportion of successful collisions.

  • Write equilibrium constant expressions, calculate Kc from equilibrium concentrations and state its units.

  • Apply Le Chatelier's principle to predict the direction of shift, and distinguish a change in equilibrium position from a change in Kc.

  • Plan a rates investigation by choosing a measurable dependent variable, five values of the independent variable and a full set of controlled variables.

Your checkpoint

A single-page factor-to-explanation-to-graph summary sheet for rates and equilibrium, checked against a 7-mark past-paper equilibrium question scored at 5/7 or better.

Week 4

Reactivity 1 - What drives chemical reactions? & Experimental programme and skills in the study of chemistry (including the internal assessment investigation)

  • Calculate enthalpy change from calorimetry data using q = mcΔT, stating the assumptions about density, specific heat capacity and heat loss.

  • Construct and use Hess's law cycles to find ΔH for reactions that cannot be measured directly.

  • Calculate ΔH from average bond enthalpies and explain why the answer differs from the value obtained using standard enthalpies of formation.

  • Define standard enthalpy of formation and combustion and write the formation equation for a named compound.

  • Design the internal assessment: write a focused research question, a variables table, a method with sufficient data points and a risk assessment.

Your checkpoint

A one-page internal assessment proposal (research question, five-level independent variable, controlled variables, method, risk assessment) submitted for supervisor feedback and approved before any data collection.

Week 5

Reactivity 3 - What are the mechanisms of chemical change? & Experimental programme and skills in the study of chemistry (including the internal assessment investigation)

  • Identify Brønsted-Lowry conjugate acid-base pairs and calculate pH, [H+] and [OH-] for strong monoprotic acids and bases using Kw.

  • Contrast strong and weak acids in terms of degree of dissociation, conductivity and rate of reaction with a metal, and sketch titration curves for strong-strong and strong-weak combinations.

  • Assign oxidation numbers, identify the oxidising and reducing agents, and balance redox half-equations in acidic solution.

  • Describe the structure and operation of a voltaic cell and a simple electrolytic cell, including electrode polarity, electron flow and the direction of ion migration.

Your checkpoint

A 20-mark mixed acid-base and redox question set scored at 80% or above, with annotated cell and titration-curve diagrams attached as the correction record.

Week 6

Structure 2 - Models of bonding and structure & Experimental programme and skills in the study of chemistry (including the internal assessment investigation)

  • Classify a substance as ionic, covalent or metallic from its position in the periodic table and explain the resulting physical properties.

  • Draw Lewis structures and apply VSEPR theory to predict shape, bond angle and polarity for species with up to six electron domains.

  • Explain the origin and relative strength of London dispersion, dipole-dipole and hydrogen bonding, and rank substances by boiling point with justification.

  • Relate giant covalent, simple molecular, ionic and metallic lattices to melting point, solubility and electrical conductivity.

  • Process the internal assessment data: calculate means, plot the graph with uncertainty bars and quantify percentage error against the theoretical value.

Your checkpoint

A completed structure-to-property comparison table for four lattice types, with a justified entry for each of melting point, conductivity, solubility in water and volatility.

Week 7

Structure 3 - Classification of matter

  • Use the periodic table to predict and explain trends in atomic radius, ionic radius, first ionisation energy and electronegativity across a period and down a group.

  • Classify elements as metals, metalloids or non-metals and link the classification to bonding type and to the acidic or basic character of their oxides.

  • Identify alkane, alkene, alcohol, aldehyde, ketone, carboxylic acid, ester, amine, amide and halogenoalkane groups from names and displayed structures.

  • Predict and name the products of simple SL reactions of those groups, including combustion, addition, oxidation, substitution and esterification.

Your checkpoint

A 20-structure quiz requiring functional group identification and IUPAC naming, scored at 90% or above.

Week 8

Experimental programme and skills in the study of chemistry (including the internal assessment investigation) & Reactivity 1 - What drives chemical reactions? & Reactivity 2 - How much, how fast and how far? & Reactivity 3 - What are the mechanisms of chemical change?

  • Finalise the internal assessment by completing data processing, uncertainty evaluation, a strengths-and-limitations discussion and a conclusion that answers the research question.

  • Sit one full-length timed SL paper under exam conditions and mark it with the official mark scheme.

  • Build a per-domain score profile from the mock and re-teach the two weakest domains with targeted questions.
