General chemistry
Balancing equations, stoichiometry, pH, yields: coursework chemistry with worked steps.
- Buffer solution, Henderson-Hasselbalch equationBuffer pH, base/acid ratio for a target pH, and the amounts to weigh for a given volume, with the buffer zone checked.
- Chemical equation balancerExact balancing of any chemical equation, linear algebra over exact fractions, with the element-by-element check displayed.
- pH calculator, acids and basesExact pH of strong and weak acids and bases, water autoionisation included. Textbook approximation computed alongside with its gap.
- Reaction yield and sample purityYield in its three directions, sample purity, molar mass and conversion into moles.
- Stoichiometry and limiting reactantLimiting reactant, masses of products formed and leftovers, from an equation that need not be balanced: the tool balances it itself.
