ChemLab: Periodic Table

ChemLab is a complete, offline chemistry toolkit for high-school and college students. Explore the full periodic table of 118 elements and solve real problems with eight built-in chemistry tools — no internet connection required. PERIODIC TABLE • All 118 elements with four levels of detail: basic properties, atomic data, electronic and physical properties, history and real-world uses. • Search by name, symbol, or atomic number. • Landscape wide view and a clear category colour legend. CHEMISTRY TOOLS • Molar Mass Calculator — get the molecular weight of any formula, with a per-element breakdown. Supports brackets and hydrates (e.g. CuSO4·5H2O). • Equation Balancer — balance any chemical equation in one tap. • Empirical Formula Calculator — find the empirical formula from mass percentages. • Molecular Formula Calculator — get the molecular formula from the empirical formula and molar mass. • Solubility Checker — look up whether an ionic compound is soluble. • Reaction Predictor — predict the products of common reactions (synthesis, decomposition, single and double replacement, combustion, neutralization). • Ion Engine — 43 ions with detailed data. • Worksheet Generator — create practice problems and export them to PDF. WHY CHEMLAB • Works fully offline — study anywhere, anytime. • Accurate: molar masses, balanced equations, and reaction products are checked so you learn the right chemistry. • Clean, fast, distraction-free interface with a dark theme. • Save favorite elements and ions, and keep a history of your calculations. PERFECT FOR • High school and college chemistry students • GCSE, A-Level, IB, AP and general chemistry courses • Anyone who needs a quick molar mass calculator, chemical equation balancer, or a molecular weight lookup on the go. Upgrade to ChemLab Pro for unlimited worksheets, PDF export, extended history, an ad-free experience, and a light theme. Learn chemistry the practical way — with a periodic table and a full set of chemistry calculators in your pocket.
