Printable Chemistry Cheat Sheet
Free printable chemistry cheat sheet at exact scale — moles and stoichiometry, gas laws, acids and bases, equilibrium, thermochemistry and common ions on one page.
This chemistry cheat sheet brings together the calculations you use most — the mole relationships (n = m/M, n = CV), the ideal gas law, dilution and concentration, pH/pOH and Ka/Kb, the Henderson-Hasselbalch equation, equilibrium constants and Le Chatelier's principle, thermochemistry and Hess's law — plus a list of common polyatomic ions and solubility rules.
It's laid out in clean columns and prints at exact scale in real millimetres on A4, Letter or any size. Great for general and AP/A-level chemistry revision.
Printing at exact scale
Every sheet is drawn in real millimetres and prints at exact physical scale. For accurate output, set Scale = 100% (Actual size) and Margins = None in your browser's print dialog. Not sure your printer is honest? Run the printer ruler test first to confirm 50 mm really measures 50 mm.
Frequently asked questions
Does it list common ions?
Yes — there's a table of common polyatomic ions with their formulas and charges, plus basic solubility rules.
What calculations are covered?
Moles and stoichiometry, gas laws, concentration and dilution, pH and buffer calculations, equilibrium constants and thermochemistry.
Is it really free?
Yes. Every template on printsheet.io is completely free, with no sign-up, no account and no watermark. Generate as many sheets as you like.
How do I get an exact-scale print?
Choose your paper size, then in the print dialog set Scale to 100% or “Actual size” and Margins to None. The sheet is defined in real millimetres, so it prints at true size. Use the calibration ruler page to verify.
Which paper sizes are supported?
A4, A5, A3, A6, US Letter, Legal and Tabloid, in portrait or landscape. Pick the size that matches the paper loaded in your printer.
Can I save it as a PDF instead of printing?
Yes — choose “Save as PDF” as the printer in your browser's print dialog. The PDF keeps the exact millimetre dimensions.
