Titration Calculator
What unknown concentration follows from equivalence-point titrant volume? Enter the stated values to calculate this model.
Reference calculation or estimate for example inputs; assumptions and limitations apply.
Calculations run in your browser.
Assumptions / Standards / Limitations
Use equivalence-point titrant volume and positive coefficients from the correct balanced reaction. Sample/titrant volumes must use the same unit. No endpoint detection, indicator selection, side-reaction or uncertainty correction is supplied.
Model reference: OpenStax Chemistry 2e; supplementary IUPAC definition where listed. Last verified: 2026-10-08. This is a scientific reference model; no regulatory code or installation standard is used.
Example inputs illustrate the calculation. They are not recommended preparation, installation or operating settings.
What to enter

Understanding your result
The result is a scientific reference calculation under the model assumptions on this page. It does not assess hazards, chemical compatibility, purity, solubility, equipment limits or clinical meaning.
Common mistakes
- Using solvent volume in place of final solution volume, or mass concentration in place of molar concentration.
- Ignoring units, reaction coefficients, activity assumptions or the stated temperature/model limits.
Check your calculation
- Check the units and balance/coefficients against the worked example. For real laboratory work, verify SDS information and the applicable procedure independently.

How it works
Relate titrant and sample amounts using the balanced-reaction coefficient ratio and the stated volumes. The reference assumes a known endpoint and stoichiometry, not an automatically validated laboratory procedure.
Worked example
Enter Titrant concentration: 0.1 mol/L; Titrant volume: 25 mL; Sample volume: 50 mL; Sample coefficient: 1 1; Titrant coefficient: 1 1. Results: Sample concentration: 0.05 mol/L.
