14 Chemistry concepts you can drag right now, grouped by topic. No account, no login. Each one is the real knowscape from knowhere, not a picture of one. Mapped to the NESA syllabus.

Alcohols
Heat of combustion and energy efficiencyExperimental values are always lower than published ones, and assessment tasks want you to explain why rather than just note it.drag it →
Analysis of Organic Substances
Proton NMR and the n+1 RuleThree pieces of information from one spectrum: shift says what kind of hydrogen, integration says how many, and splitting says how many hydrogens…drag it →
Calculating the Equilibrium Constant (Keq)
ICE TablesInitial, Change, Equilibrium.drag it →
Chemical Synthesis and Design
Green Chemistry in Drug SynthesisPharmaceutical synthesis generates more waste per kilogram of product than almost any other industry.drag it →
Hydrocarbons
Fossil Fuels and Biofuels ComparedBoth burn, both release CO₂, but only one is replaced on a human timescale.drag it →
Nomenclature
IUPAC nomenclatureA systematic name is a set of instructions for rebuilding the molecule.drag it →
Polymers
Polymer structure and physical properties relationshipLinear polymers like high-density polyethene contain unbranched chains that pack efficiently creating crystalline regions with strong…drag it →
Products of Reactions Involving Hydrocarbons
Addition Reactions of AlkenesA double bond is stored reactivity.drag it →
Properties of Acids and Bases
Acid-base indicatorsIndicators are weak acids whose two forms wear different colours - the ratio flips with pH, and the colour flips with it.drag it →
Quantitative Analysis
Volumetric analysisA titration is stoichiometry with a burette.drag it →
Reactions of Organic Acids and Bases
Esters and EsterificationCarboxylic acid plus alcohol, a dash of sulfuric acid, gentle heat - and out comes an ester, the family behind fruit smells and flavours.drag it →
Solution Equilibria
Solubility Equilibria and Ksp (Solubility Product)Even 'insoluble' salts dissolve a little, and where dissolving stops is an equilibrium with its own constant: Ksp.drag it →
Static and Dynamic Equilibrium · Factors that Affect Equilibrium
Collision theoryReactions need collisions — but most collisions do nothing.drag it →
Using Brønsted–Lowry Theory
pH and the ion product of waterPure water self-ionises into equal tiny amounts of H+ and OH- ions giving pH 7, and the product of these concentrations always equals 1.0 times 10…drag it →
