Chemistry formula sheets, charts and tables for quick revision
Chemistry Study Guide is a quick-reference app for revising chemistry. Instead of long lessons, every topic is condensed into charts, tables, formula boxes and short key points, with a worked example where it helps and a few practice questions with tap-to-reveal answers.
What the app covers
• Units and Stoichiometry: SI units and prefixes, key constants (CODATA 2022), conversions, mole and stoichiometry formulas, concentration units
• Atoms and the Periodic Table: light and quantum formulas, the Bohr model, quantum numbers, filling rules and electron configurations, periodic trends, magnetic properties
• Bonding and Structure: bond types, Lewis structures and formal charge, VSEPR shapes, hybridization, sigma and pi bonds, molecular orbital theory, intermolecular forces and types of solids
• Gases and Phases: gas laws, kinetic theory, Graham's law, real gases, phase changes, phase diagrams, Clausius–Clapeyron equation
• Solutions: solubility, Henry's law, Raoult's law, colligative properties, the Beer–Lambert law
• Thermodynamics: the laws of thermodynamics and sign conventions, enthalpy, calorimetry, Hess's law, entropy and Gibbs energy
• Kinetics: rate laws, reaction orders, integrated rate laws, half-lives, the Arrhenius equation and catalysts
• Equilibrium: equilibrium constants, reaction quotient, ICE tables, Le Chatelier's principle, solubility products
• Acids and Bases: definitions, strong acids and bases, pH and buffer formulas, what makes an acid strong, titrations and indicators
• Inorganic Charts: solubility chart, precipitate colours, activity series, flame tests, colours of ions, metallurgy
• Redox and Electrochemistry: oxidation numbers, balancing redox equations, galvanic and electrolytic cells, standard potentials, the Nernst equation, Faraday's laws
• Nuclear Chemistry: types of decay, nuclear equations, half-life and radiocarbon dating, binding energy, fission and fusion
• Organic Chemistry: hydrocarbons and naming, functional groups and tests, isomerism, CIP priority rules (R/S and E/Z), aromaticity, SN1, SN2, E1 and E2 reactions
