What you can investigate
Explore pH, H⁺, OH⁻, strong and weak acids by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.
Relate hydrogen-ion concentration to pH and acid–base strength.
This browser-based simulation helps you relate hydrogen-ion concentration to pH and acid–base strength. Designed for Grades 8–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.

A typical investigation takes 7–12 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
Relate hydrogen-ion concentration to pH and acid–base strength. The main ideas are pH, H⁺, OH⁻, strong and weak acids.
Yes. You can run the simulation online for free without creating an account.
Most learners can complete one investigation in 7–12 min. You can repeat it to compare more variables or improve your explanation.
