Description

The app allows to discover chemical reactions and to solve the chemical equations with one and or unknown variables. You'll always have Mendeleev's Periodic Table and Solubility table handy. And even the calculator of molar masses!

The app discovers the equations of chemical reactions even if the right or left part is unknown, helps you with organic and inorganic chemistry. The discovered reactions in an usual and ionic aspect will be mapped and formulas of organic chemistry are drawn for you.

Convenient interactive Periodic Table. Tap a chemical element in the table to look the information.

The calculator of molar masses. Enter correctly a chemical compound and it will show molar masses and percentage of elements.

The table of solubility of substances is added in the app as well as Acid strength chart. Now your textbooks become waste!

The best solver of chemical equations for iPhone and iPad.

All these tables and charts are available in the app for free:
* Periodic table
* Chemical reactions search
* Solubility table
* Molar mass calculator
* Electronegativity of elements
* Molecular weights of organic substances
* Reactivity series
* Acid strengths chart

 Free in iOS App Store
