IGCSE Chemistry Formula Sheet and Key Equations Singapore
An IGCSE chemistry formula sheet helps you recall key equations and constants in the exam. This guide summarises the type of formulae and equations that appear on Cambridge and Edexcel IGCSE Chemistry and how to use them for revision in Singapore.
What is on an IGCSE chemistry formula sheet?
Formula sheets for IGCSE Chemistry usually list equations for moles, concentration, gas volume, energy changes, and key constants (e.g. Avogadro constant, gas constant). Exam boards may provide an official sheet in the exam or require you to memorise some formulae. Check your syllabus and past papers to see what is given and what you must learn. Cambridge and Edexcel may differ slightly, so use the correct formula list for your exam board.
Key topic areas
Moles and stoichiometry: Equations linking moles, mass, and molar mass; concentration and volume. Acids and bases: pH and concentration; neutralisation. Rates of reaction: Factors and calculations. Organic chemistry: Formulae for organic compounds and reactions. Electrochemistry: Redox and electrolysis equations. Practise using the formulae with past paper questions so you know when and how to apply them; formula sheets are only useful if you understand what each equation means and when to use it.
Where to get formula sheets
Your teacher or exam board website often provides a formula list. Use official Cambridge or Edexcel resources. Do not rely on unofficial sheets without checking they match your syllabus and series. Combine with IGCSE past papers and tuition for full preparation. For IGCSE Physics formula sheets, see our IGCSE physics formula sheet guide.
Using the chemistry formula sheet in the exam
In the exam, if you are given an IGCSE chemistry formula sheet, use it as a reference: do not waste time memorising formulae that are on the sheet, but do know where each one is and when to use it. If some formulae are not on the sheet, you must learn them. Practise past papers with the same formula sheet (or the one your teacher gives you) so you are used to finding the right equation quickly. For Singapore students, combining the formula sheet with IGCSE past papers and, if needed, IGCSE Chemistry tuition (e.g. on Tutopiya) helps you apply the formulae correctly under exam conditions.
