What is the Acid-Base Titration Simulator?
Run a full analytical titration bench: fill the burette, add titrant drop by drop or continuously, and watch the live pH meter and titration curve build as you go. It runs in your browser, so a change to a setting or a drag on an object shows up at once.
Titration is used in water testing, food labs, medicine and industry to find unknown concentrations accurately. Pharmacies and quality-control labs run titrations every day.
3 steps to your result
Open the tool and follow along. Nothing to install.
What you get
The equivalence point is where moles of titrant added equal moles of analyte.
Strong acid with strong base has its equivalence point at pH 7.
Weak acid with strong base has its equivalence point above pH 7 and a buffer region before it, centred on the half-equivalence point where pH = pKa.
Titrate a strong acid, then repeat with a weak acid.
Find the equivalence volume for 0.10 M acid and 0.10 M base.
Choose the best indicator for the weak acid and watch the warning if you pick the wrong one.

For teachers: project the Acid-Base Titration Simulator on the board, let students predict the result, then run it together and test this: Find the equivalence volume for 0.10 M acid and 0.10 M base. For students: change one thing at a time and write down what changes.

Questions people ask
What is the equivalence point?
The point in a titration where the amount of titrant added exactly reacts with the analyte. It shows as the steepest part of the pH curve and as a sharp peak on the derivative graph.
Which indicator should I use?
Choose an indicator whose colour-change range includes the pH at the equivalence point. Phenolphthalein suits weak acid with strong base; methyl orange suits weak base with strong acid.
What is the half-equivalence point?
The point where exactly half the analyte has reacted. For a weak acid or base, the pH there equals the pKa (or 14 − pKb), by the Henderson-Hasselbalch equation.
Is the Acid-Base Titration Simulator free to use?
Yes. The Acid-Base Titration Simulator is free, needs no signup or download and runs in your web browser. It is part of the Chemistry Labs group of AZRS simulations.
Does the Acid-Base Titration Simulator work on a phone or tablet?
Yes. The Acid-Base Titration Simulator takes touch input as well as mouse input, so you can use its 9 adjustable settings with a finger. A larger screen makes the controls and graphs easier to read.
