An interactive lesson with 4 steps, about 5 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Buffers absorb acid or base until one form runs out.
• Capacity grows with concentration.
• Track amounts (mmol): added H⁺ turns A⁻ into HA.

Steps

1. Water versus buffer
2. Strong enough
3. Running out
4. Count the protons
