Titration Stoichiometry Calculator
At equivalence, reacting amounts follow the balanced equation. Volumes may both be entered in cm³ because the common conversion cancels.

Step-by-step working
The formula
n_A = C_AV_A
n_A/ν_A = n_B/ν_B
C_B = C_AV_Aν_B/(ν_AV_B)
| Symbol | Meaning |
|---|---|
| ν | Stoichiometric coefficient from the relevant balanced reaction. |
| V | Use matching volume units in the ratio. |
When to use this calculator
This calculator assumes the endpoint volume represents equivalence for the stated stoichiometry. Acid–base and redox titrations can have coefficients other than 1:1.
Worked example
The page opens with these example values. The result below is pre-generated for reference.
- V_A = 0.025 dm³; n_A = C_AV_A = 0.1 × 0.025 = 0.0025 mol
- n_A/ν_A = n_B/ν_B, so n_B = 0.0025 × 1/1 = 0.0025 mol
- V_B = 0.0246 dm³; C_B = n_B/V_B = 0.0025 / 0.0246 = 0.101626 mol dm⁻³
- Suggested reporting from the measured inputs: 0.1016 mol dm⁻³ (4 significant figures).
0.1016 mol dm⁻³
Common mistakes
- Do not assume equal moles unless the equation is 1:1.
- Average concordant titres according to the method required by your course/teacher before substitution.
