A simple app designed as a quick reference for chemistry students. Includes a periodic table with links to wikipedia, a tool to calculate molecular masses of compounds (with a button at the top to perform simple grams/moles calculations, calculate mass percents and do stoichiometry with that compound), a table of polyatomic ions, constants, solubility rules, tools for calculating molarity and volume of solutions, tools for converting between units commonly used in chemistry, compound lookup that links to major chemical search engines (and wikipedia, of course), a table of reduction potentials, organic chemistry functional groups, IR, 1H NMR and 13C NMR spectroscopy tables and a table with common ligands.
