ChemLab Assistant

ChemLab is your pocket laboratory assistant, built for students, researchers and lab technicians. Every essential chemistry calculation, two taps away — 100 % offline, no account, no connection required. ⚗️ QUICK CALCULATIONS • Molarity: C = n / V (leave any field blank to solve for it) • Dilution: C1·V1 = C2·V2 • Conversions: grams ↔ moles, mg/L ↔ ppm, % m/V 🧪 STEP-BY-STEP LAB ASSISTANT • Prepare a solution from a chemical formula (e.g. NaCl, H2SO4, Ca(OH)2) • Guided dilution with full procedural instructions • Concentration adjustment: too dilute or too concentrated → fix 🔬 ADVANCED CHEMISTRY • pH: strong acids/bases, weak acids (Ka), Henderson-Hasselbalch • Stoichiometry: limiting reagent, % yield • Ideal gas law PV = nRT • First-order kinetics, half-life • Radioactivity: decay, t½, activity (Bq) • Formula parser: Al2(SO4)3, CuSO4·5H2O 📚 LOCAL HISTORY Every calculation is saved on your device — nothing leaves your phone. Browse, delete, reuse. 🌐 BILINGUAL EN / FR Switch language with a single tap. ✨ MODERN DESIGN Clean interface, soft gradients, intuitive navigation. Works on Android 7.0+. ChemLab is free and ad-supported. Thank you for keeping the app alive!
