Chemist Free

Your chemistry studies are only as good as your reference tool. Chemist Free eliminates guesswork, providing instant access to a complete periodic table, molar mass calculator, and solubility rules — all offline.

Core Reference Tools & Calculators

Chemist Free transforms your Android device into a portable chemistry workstation. The app delivers a fully interactive periodic table with element-by-element data, including atomic mass, electron configuration, electronegativity, and oxidation states. Tap any element to view its complete properties, physical constants, and isotopic abundance.

The built-in molar mass calculator processes chemical formulas in real time. Enter H2SO4 or C6H12O6 and the app instantly returns molecular weight, elemental composition by percentage, and empirical formula derivation. The solubility table covers over 200 common ionic compounds, categorizing them as soluble, slightly soluble, or insoluble in water.

• Interactive Periodic Table — Scrollable table with 118 elements, color-coded by group, block, and state of matter.
• Molar Mass Calculator — Parses complex chemical formulas and returns mass, composition, and empirical ratio.
• Solubility Reference — Searchable chart of ionic compounds with solubility rules and exceptions.

Practical Study & Problem-Solving Tools

The app includes a balanced equation viewer that displays common chemical reactions, complete with state symbols and reaction conditions. A built-in unit converter handles pressure (atm, kPa, mmHg), temperature (Celsius, Kelvin, Fahrenheit), and concentration (molarity, molality, normality).

Students and professionals benefit from the quick-reference glossary covering 500+ chemistry terms, definitions, and formulas. The reaction type classifier identifies synthesis, decomposition, single displacement, double displacement, and combustion reactions from user-submitted equations.

Performance & Usability

Chemist Free operates entirely offline after initial installation — no internet connection required for any core feature. The interface loads in under 2 seconds on devices running Android 2.2.x and above. Touch targets measure at least 48dp, ensuring accurate tapping on small screens. The app supports both portrait and landscape orientations, with UI elements that scale proportionally across phone and tablet resolutions.
