Store description excerpt

Chemie begreifen makes upper-secondary chemistry make sense — not by memorizing, but by working with the quantities and seeing immediately what happens. The app is in German. Written for upper-secondary students, explicitly including those who have lost the thread. Next to every technical term sits an info button. One tap brings up a plain-language explanation with a worked example and links down to the underlying basics. You don't need to know what to search for — the explanation is right where the term appears. PERIODIC TABLE All 118 elements, tappable, with atomic number, molar mass, electron configuration, shell occupation and electronegativity. Switch the colouring between substance class, electronegativity and state of matter. Search by name, symbol or atomic number. LABORATORY Tap two elements and see what forms: which salt, which electrons move, why the ratio is exactly what it is. Plus over twenty verified reactions from the oxyhydrogen reaction through the Haber-Bosch process to photosynthesis, each with conditions, energy balance and everyday relevance. STOICHIOMETRY Molar mass from any formula including brackets and water of crystallization, with the calculation broken down rather than just an answer. Conversion between mass, amount of substance, particle number and gas volume. Solution preparation and dilution. And an equation balancer that solves rather than guesses. ACIDS AND BASES pH values for strong and weak acids, buffers via Henderson-Hasselbalch, and titration curves with equivalence and half-equivalence points. The school-level approximation and the exact value always appear side by side — along with a note on whether the approximation holds here at all. REDOX AND ELECTROCHEMISTRY Oxidation numbers for any formula, derived step by step rather than looked up. Analyse reactions to see what is oxidized and what is reduced. Electrochemical series, cell voltage, the Nernst equation and Faraday's laws. ORGANIC CHEMISTRY Pick a substance class and chain length, and the name, molecular formula, condensed formula and drawn skeletal formula follow from it. The name is not vocabulary but a set of building instructions — and that becomes visible here. Plus homologous series with boiling point trends and isomer counts. WHAT THIS APP DOES NOT DO It never invents anything. Where a result cannot be derived soundly, it says so and explains why, instead of producing a plausible-looking but wrong answer. For exam preparation, an honest gap is worth more than a fabricated answer. The calculation logic is machine-verified: over four thousand automated checks compare molar masses, balances, pH values, oxidation numbers and nomenclature against reference values before any version is built. PRIVACY Chemie begreifen collects no personal data whatsoever. No accounts, no ads, no in-app purchases, no tracking, no internet connection required. Inputs stay temporarily on your device only.
