Acid-Base Titration

Add base to an acid drop by drop and watch the pH curve rise, then leap through the equivalence point where the two exactly neutralize.

Acid–Base TitrationLive

Controls

Add base to an acid and track the pH. The steep jump marks the equivalence point, where moles of acid equal moles of base.

Equivalence50.0 mL
Typestrong acid + strong base
pH at eq.7.0

Governing equation

Reading this result: Equivalence sits near 50.0 mL; because this is a strong acid with a strong base, the pH there is exactly 7 and the jump is nearly vertical.

How it works

This models a strong-acid, strong-base titration by tracking moles of H+ and OH- as titrant is added. The steep vertical jump marks the equivalence point; its volume follows directly from the concentrations, the core calculation of quantitative chemistry.

Frequently asked questions

Is this titration curve tool really free?
Yes. Acid-Base Titration runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.
Do I need to install anything?
No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.
Can I save or share my simulation?
Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.
How accurate are the results?
The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
