About

Stoichiometry

This tool helps balance chemical reactions and calculate molar masses, moles, and actual masses of reactants and products. It supports various formula formats and can identify limiting reagents. Data can be sent to another app for gas phase calculations.

Highlights
  • Balance chemical reactions
  • Calculate molar masses
  • Determine moles and actual masses
  • Identify limiting reagents
  • Supports various formula formats
  • Integrates with Gas Phase Stoichiometry app

Read full description

Stoichiometry is an ultimate tool for balancing chemical reactions, finding molar masses, moles and actual masses of reactants and products based on their chemical formulas, stoichiometric coefficients and any quantitative data provided, that available on Apple Store for iOSΒ and Mac . It is enough to provide initial or final (after reaction accomplishment) mass or moles of one of the reaction component, to calculate all required and obtained masses and moles of all components. If data is available for several components, then limiting reagent will be found based on reaction stoichiometry. Molecular formula format: charge or unpaired electrons (in free radicals), if exist, must be provided as well, separated by coma: Na,+ ; R,: ; SO4,2- . Application supports state indexes: (g), (s), (l), (aq) – all are lowercase only, placed at the end of compound formula. App can send the data toΒ  Gas Phase Stoichiometry app to further calculate pressures and volumes of gaseous compounds. Either moles or masses can be filled in, but if by mistake both are provided and they don’t match, then the moles value will have a preference. Component will be taken into consideration once the stoichiometric coefficient is provided for it. For balancing redox reactions please refer to Electrochemistry application.

Verdict

The call

The clearest difference is update cadence: Stoichiometry at every 2 months against Column Construction Calculator's every 38 months. Column Construction Calculator's advantage is price ($1.99 vs $2.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
