pH Calculator
Choose a strong or weak acid or base, or a buffer, and see the pH on a scale with the working. Common acids and their Ka values are built in.
What you can do
- Strong and weak acids and bases, including very dilute solutions
- Find Ka and pKa from a measured pH
- Buffers with the Henderson-Hasselbalch equation
- Shows how much of a weak acid is ionised at this pH on a species graph
- Practise with random questions and worked solutions
