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
