Titrating a Weak Acid

Reading pKa off a curve

An interactive lesson with 5 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

• Weak acid titration: buffer region, then a jump; equivalence pH > 7.
• At half-equivalence, pH = pKa.

Steps

1. A different curve
2. Run the titration
3. Half-way there
4. Why above 7?
5. An unknown acid
