About the Titration calculator
Calculate the unknown concentration or the required titrant volume for acid-base, redox and complexometric titrations.
How to use the Titration calculator
- Choose the Titration type and Scenario, and what to Solve for.
- Enter the analyte concentration and volume and the titrant concentration or volume.
- Press Calculate.
Formula and method
For a 1:1 reaction at the equivalence point: C₁ × V₁ = C₂ × V₂.
Worked example
25 mL of 0.1 M HCl needs 25 mL of 0.1 M NaOH to reach the equivalence point.
Tips
- Adjust for reactions that are not 1:1.
- Repeat titrations and average the concordant results.
Frequently asked questions
What is the equivalence point?
The point where the amount of titrant exactly reacts with the analyte.
