HSC Chemistry Formula Sheet 2026
The official NESA data sheet — formulas, solubility data, spectroscopy tables and standard potentials — and how to actually use it fast.
NESA provides an official Chemistry data sheet in every HSC Chemistry exam — formulas, solubility constants, IR/NMR/UV reference tables, standard electrode potentials and a periodic table, current for 2026. Get it directly from NESA using the link above; that’s always the authoritative, up-to-date version. What actually costs students marks isn’t not having the sheet, it’s not knowing which table to check for a given question, or misreading data (a wrong sign on a standard potential, the wrong solubility constant row). This page focuses on that — how to use the sheet quickly and correctly by module — rather than reproducing NESA’s document.

Reference Guide: The data sheet is handed out with every HSC Chemistry paper, so you never need to memorise the formulas, constants or reference tables — but exam questions rarely tell you which part of the sheet to check. Examiners expect you to recognise, from the wording of a question, whether it needs a formula calculation, a solubility/electrode-potential lookup, or a spectroscopy data table — and to read the right row correctly under time pressure. That recognition and reading-under-pressure skill is what the module breakdown below and Revizi’s practice questions target.
Topics Covered
Module 5: Equilibrium and Acid Reactions
- Equilibrium constant and concentration/molarity formulas
- Le Chatelier’s principle questions — no calculation needed, don’t reach for a formula unnecessarily
- pH and pKa calculations from the formulas sheet
Module 6: Acid/Base Reactions
- pH, pOH and buffer calculations
- Titration curve interpretation alongside pH formulas
- Checking whether a question needs a calculation or a conceptual acid-base explanation
Module 7: Organic Chemistry
- Infrared (IR) absorption data table — matching wavenumber ranges to functional groups
- ¹³C NMR chemical shift table — matching carbon environments to δ values
- UV absorption data for identifying chromophores
Module 8: Applying Chemical Ideas
- Standard electrode potentials table — check the sign and direction of the half-reaction as written
- Solubility constant (Ksp) table for precipitation and solubility questions
- Enthalpy/entropy/Gibbs free energy formulas (ΔG° = ΔH° − TΔS°) for spontaneity questions

How Revizi Helps
NESA Syllabus Alignment
Questions are organised around NESA syllabus outcomes and content points.
Active Recall Revision
Flashcards test your knowledge using active recall — more effective than re-reading notes.
Performance Insights
Track accuracy across modules and question types to focus your remaining study time.
Common Mistakes to Avoid
- Using the wrong sign convention when reading standard electrode potentials off the table — the direction the half-reaction is written matters
- Reaching for the solubility constant table when a question is actually about equilibrium concepts, not a Ksp calculation
- Misreading an IR or NMR data table row — checking the wrong wavenumber range or chemical-shift band for the functional group in question
- Not checking units before substituting into a formula — the sheet’s constants are in SI units
Study Tips
- Don’t try to memorise the sheet’s layout — you’re given it in the exam. Instead, practise quickly locating the right table or formula for a given question type.
- Practise reading the spectroscopy tables (IR, NMR, UV) specifically — they’re easy to misread under time pressure and are unique to Chemistry compared to other HSC science data sheets.
- Work through official NESA past papers using the real data sheet (linked above) under timed conditions, so exam day isn’t the first time you’ve used it under pressure.

Frequently Asked Questions
Where can I get the official HSC Chemistry data sheet?
Directly from NESA — see the official link above. It’s provided to every student in the actual HSC exam, so always check NESA’s current version yourself before exam day rather than relying on any third-party copy.
Does Revizi host or reproduce NESA’s data sheet?
No. Get the official sheet from NESA using the link on this page. Revizi’s content here is original — a module-by-module guide to which formulas and tables apply where — not a copy of NESA’s document.
What’s on the HSC Chemistry data sheet besides formulas?
Solubility constants, infrared absorption data, ¹³C NMR chemical shift data, UV absorption data, standard electrode potentials, and a periodic table — not just equations. Knowing which table to check for which question type is as important as knowing the formulas.
What’s the best way to practise using the data sheet?
Work through official NESA past papers using the real data sheet under timed conditions to build speed finding the right formula or table. Use Revizi’s module-by-module practice questions to drill whichever module you’re weakest on.
