ChemLab: Periodic Table

ChemLab is an all-in-one chemistry app with a periodic table, equation balancer, molar mass calculator, ion reference, solubility checker, formula tools, reaction predictor, and worksheet generator. Built for students, teachers, and exam prep, ChemLab helps you study chemistry faster with accurate results and a clean, easy interface.

Study for class, review before exams, solve formulas, explore the elements, and generate chemistry practice worksheets in one app.

INTERACTIVE PERIODIC TABLE

• Explore all 118 elements with 4 levels of detail

• View atomic structure, electron configuration, physical properties, discovery history, and real-world uses

• Pinch to zoom, tap for details, and use landscape wide-view mode

• Filter by element group, metal type, and state of matter

EQUATION BALANCER

• Balance chemical equations automatically with matrix-based math

• Supports hydrates, nested formulas, and state symbols: (s), (l), (g), (aq)

• Fast, accurate results for simple and complex equations

• Great for homework, revision, and classroom use

MOLAR MASS CALCULATOR

• Calculate molar mass for chemical formulas in seconds

• See a full breakdown by element: count, atomic mass, subtotal, and percentage

• Supports formulas like H2O, Ca(OH)2, Al2(SO4)3, and CuSO4·5H2O

• Clear formula display makes results easy to read

ION REFERENCE

• Study 40+ ions with detailed information pages

• Includes monatomic ions, polyatomic ions, and transition metal ions

• Search and filter quickly by symbol, charge, or ion type

• Learn charge patterns and common chemistry behavior

SOLUBILITY CHECKER

• Check whether compounds are soluble, insoluble, or slightly soluble

• Guided mode helps beginners choose ions without memorizing rules

• Expert mode makes lookup faster for advanced users

• Covers key solubility rules including nitrates, sulfates, hydroxides, and carbonates

FORMULA TOOLS

• Empirical Formula Calculator for converting mass percentages to the simplest formula

• Molecular Formula Calculator for finding the actual formula from empirical formula and molar mass

• Step-by-step ratio display helps you understand the method, not just the answer

REACTION PREDICTOR
