Reaction & Stoichiometry Tools
Balance equations, predict products, and scale a reaction from one known amount.
Once the equation is balanced, these tools carry the rest of the calculation: predict the products of common reaction types, convert grams of one species into grams of another, derive an empirical formula from elemental mass percentages, get a molecular formula from an empirical formula plus molar mass, and simulate a titration curve to locate the equivalence point.
Reaction Product Predictor
Enter reactant names to look up compounds via PubChem and predict products of common reactions (combustion, acid-base) with a balanced equation.
Open tool →Chemical Equation Balancer
Balance a chemical equation automatically. Find stoichiometric coefficients (e.g. H2 + O2 -> H2O).
Open tool →Stoichiometry Calculator
Calculate reactant and product moles and masses from a balanced chemical equation — enter coefficients and formulas, then specify one known mass.
Open tool →Empirical Formula Calculator
Determine the empirical formula of a compound from elemental mass percentages. Converts each element to moles and simplifies to the smallest whole-number ratio.
Open tool →Molecular Formula Calculator
Determine the molecular formula from an empirical formula and molar mass. Calculates the integer multiplier and the full molecular formula.
Open tool →Titration Curve Calculator
Simulate strong- and weak-acid titrations with a strong base — plot the pH curve and find the equivalence point.
