IB Diploma Programme (DP) Chemistry help — done properly
IB Chemistry SL covers 11 core topics; HL adds depth on bonding, energetics, kinetics, equilibrium, redox, and organic. The 4 options (A: Materials, B: Biochemistry, C: Energy, D: Medicinal Chem) add another paper-3 worth of content. Choose your option early.
Exam format you'll actually sit
SL: 3 papers (45 min, 1.25h, 1.25h, 80 marks). HL: 3 papers (1h, 2.25h, 1.25h, 110 marks). All require Data Booklet (provided).
Highest-yield topics (the ones that show up year after year)
- Stoichiometric relationships (mole concept)
- Atomic structure + periodicity
- Chemical bonding + structure
- Energetics + thermochemistry (Hess's law, bond enthalpies)
- Kinetics + equilibrium (Le Chatelier, Kc, Kp)
- Acids and bases (pH, Ka, Kb, titration curves)
- Redox + electrochemistry
- Organic chemistry (mechanisms in HL)
Drill these first. If you can't do every one of these cold, work through them with /explain or /problem-variants.
Common mistakes that quietly cost marks
- Mole calculations: not balancing equations first
- Bond enthalpies: signs (bonds breaking = +, bonds forming = −)
- pH calculations: confusing strong vs weak acid formulas
- Organic mechanisms: missing curly arrows (especially for SN2)
- Data Booklet: forgetting it has the equation you need (always check)
When you mark your past papers, tag each lost mark to one of these. The pattern reveals where to focus.
