Acid–Base Titration
by Anonymous · ⭐ 1 · 🍴 0
Add base drop by drop to an acid and find the exact equivalence point. Adjust the volume to see which remains—acid or base—and explore by hand why the pH curve rises sharply near equivalence, and when methyl orange, BTB, and phenolphthalein change color.

About this app
An interactive high school chemistry simulation of strong acid–base neutralization titration using HCl and NaOH. Adjust the volume of NaOH added to see whether acid or excess base remains, locate the equivalence point at 20 mL, and observe how pH changes across the titration. A separate indicator view compares the color-change behavior of methyl orange, BTB, and phenolphthalein near the endpoint.
Use cases
- High school chemistry students learning titration
- Teachers demonstrating equivalence points and neutralization
- Learners exploring acidic, neutral, and basic solutions
- Reviewing pH curves and indicator selection
Features
- Stepwise NaOH volume control with acid, equivalence-point, and excess-base states
- Interactive pH curve showing the steep change near pH 7
- Indicator comparison for methyl orange, BTB, and phenolphthalein
- Visual color-change ranges and endpoint states
- Guided missions with reset and next controls
