Add base to an acid and the pH barely budges — until it suddenly leaps at the equivalence point. Watch that dramatic jump form as you change the concentrations.
Acid–Base TitrationLive
the pH jump at equivalence
Controls
Presets
Adding base to an acid barely moves the pH until you approach the equivalence point, where it leaps almost vertically. That steep jump is what makes an indicator color change so sharp. Educational tool.
Reading this result: Starting at pH 1.00, the curve stays flat until it leaps through pH 7 at the equivalence volume of 25.0 mL, where moles of base equal moles of acid.

How it works
A titration tracks pH as one solution is added to another. For a strong acid and strong base, the pH climbs slowly, then jumps almost vertically through pH 7 at the equivalence point where moles of acid equal moles of base — the signal an indicator uses to change color. Educational tool.

Is this titration curve simulator 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.
