Questions about the Chemistry posters
- What is the Chemistry section of LearnPosters?
- The rules, mechanisms and constants of a chemistry degree. Bonding, equilibria, organic mechanisms and the analytical methods — the reference sheets that live on a lab bench.
- What topics do the Chemistry posters cover?
- 100 posters across 7 topics. General chemistry — Atoms, bonding, stoichiometry and gases. Organic — Functional groups, mechanisms and synthesis. Inorganic — Periodicity, coordination and solid state. Physical chemistry — Thermodynamics, kinetics and quantum basics. Analytical — Titrations, spectroscopy and chromatography. Lab practice — Technique, safety and measurement. Calculations — Moles, concentrations, yields and equilibria.
- Who are the Chemistry posters for?
- The chemistry charts are pitched at undergraduates and professionals — the frameworks and equations a course keeps returning to. Nothing here is tied to a school year, so a curious beginner and someone revising the same material for an exam are looking at the same chemistry chart.
- Which Chemistry poster should I print first?
- Atomic Structure, Electron Configuration and Periodic Trends are the ones people reach for first — they are the references the rest of the chemistry set assumes you already have on the wall.Atomic StructureElectron ConfigurationPeriodic Trends
- Are the Chemistry posters free to print?
- Yes — all 100 of them. Each chemistry poster is a free vector PDF that needs no account, prints on US Letter or A4, and enlarges to A1 without softening. Home, classroom, library and tutoring use are all covered by the licence.Read the licence
