WACE Chemistry ATAR study plan

WACE Chemistry ATAR · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Chemical reactions, stoichiometry and the mole concept

  • Write and balance full, ionic and net ionic equations for precipitation, neutralisation and gas-forming reactions, including state symbols.

  • Convert confidently between mass, moles, molar volume and concentration for solids, solutions and gases at STP and non-STP conditions.

  • Solve limiting-reagent and percentage-yield problems from a written description without prompts.

  • Perform a full titration calculation chain (average titre, moles, concentration, dilution factor) from raw data.

Your checkpoint

A 20-question self-marked problem set on stoichiometry and solution calculations, scored and error-logged, with every wrong item reworked to a correct full solution.

Week 2

Structure of the atom and the periodic table & Chemical bonding and molecular shape

  • Explain periodic trends in atomic radius, ionisation energy, electronegativity and metallic character using shell number, nuclear charge and shielding.

  • Write full and condensed electron configurations and derive ion configurations for main-group elements.

  • Predict bond type from electronegativity difference and justify the prediction with a model of electron distribution.

  • Draw Lewis structures and use VSEPR to assign shapes and bond angles for up to six electron domains, including lone-pair distortions.

  • Relate polarity of molecules to shape and predict which substances will dissolve in water.

Your checkpoint

A one-page summary table of trends plus a set of 15 molecular shape and polarity determinations, each justified in one sentence.

Week 3

Chemical reactions, stoichiometry and the mole concept & Acids, bases and salts

  • Classify substances as strong, weak or non-electrolytes and link this to degree of ionisation.

  • Perform pH, pOH and dilution calculations for strong acids and bases, and use Ka expressions qualitatively for weak acids.

  • Design and describe a titration procedure including indicator choice for a strong acid-weak base system and justify the choice.

  • Explain buffer action and hydrolysis of salts in terms of proton transfer equilibria.

  • Predict the products of acid-carbonate, acid-metal and acid-base reactions and write balanced equations for each.

Your checkpoint

A written practical report (600 words) for an acid-base titration including method, results table, calculation and an indicator-choice justification.

Week 4

Redox reactions and electrochemistry

  • Assign oxidation numbers and identify oxidant, reductant, and the half-equations for a given redox reaction.

  • Balance complex redox equations in acidic and basic media using the half-equation method.

  • Construct and label galvanic cell diagrams, writing anode, cathode and overall cell equations and calculating E°cell.

  • Predict spontaneity from standard reduction potentials and explain the role of the salt bridge.

  • Explain electrolysis of molten and aqueous systems, writing electrode half-equations and predicting products.

Your checkpoint

A completed redox and electrochemistry test of 15 items with half-equations, cell potentials and electrolysis predictions, self-marked against a written answer key.

Week 5

Thermochemistry and energy changes & Rates of reaction and chemical equilibrium

  • Calculate enthalpy change from calorimetry data and from Hess's law cycles, including bond-energy and formation-enthalpy routes.

  • Draw and interpret potential energy profiles for exothermic and endothermic reactions with and without a catalyst.

  • Apply collision theory to explain the effect of concentration, temperature, surface area, pressure and catalyst on rate.

  • Write and manipulate equilibrium constant expressions and use Le Chatelier's principle to predict the direction of shift.

  • Solve equilibrium calculations for Kc and for simple ICE-table problems.

Your checkpoint

A two-part worked portfolio: three Hess's law and calorimetry problems plus three equilibrium calculations, each with a labelled energy diagram or ICE table.

Week 6

Organic chemistry and functional groups

  • Identify and name functional groups including alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids, esters, amines and amides using IUPAC conventions.

  • Draw and name structural isomers for a given molecular formula, including chain and position isomers.

  • Predict the products of addition, substitution, oxidation, esterification and condensation reactions and write balanced equations.

  • Distinguish primary, secondary and tertiary alcohols and predict their oxidation products.

  • Explain the physical properties of organic families in terms of hydrogen bonding and chain length.

Your checkpoint

A functional-group identification and reaction-prediction worksheet of 25 items, fully named and balanced, with a short isomer set for one formula.

Week 7

Chemical reactions, stoichiometry and the mole concept & Redox reactions and electrochemistry & Organic chemistry and functional groups

  • Solve integrated problems combining organic reaction equations with mole and yield calculations.

  • Combine redox half-equations with stoichiometric calculations for titrations involving permanganate or dichromate.

  • Interpret unfamiliar data sets and experimental descriptions to identify the underlying concept being tested.

Week 8

Chemical analysis and laboratory skills & Structure of the atom and the periodic table & Chemical bonding and molecular shape & Acids, bases and salts & Thermochemistry and energy changes & Rates of reaction and chemical equilibrium

  • Select and justify separation and identification techniques, including filtration, distillation, chromatography and spectroscopy, for given scenarios.

  • Evaluate experimental design for validity, reliability and accuracy, identifying sources of error and improvements.

  • Revise weak areas flagged in earlier error logs with targeted re-testing.
