Frequently asked questions
What if the ratio isn't 1:1?
For H2SO4 versus NaOH use 0.5 — check the balanced equation.
Why repeat titrations?
Concordant titres within 0.1 mL confirm the endpoint is reliable.
What do I need to enter into the Titration Calculator?
Just 4 values: titrant concentration, titrant volume, analyte volume, mole ratio (analyte:titrant). Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Titration Calculator work out the answer?
At the equivalence point, moles of titrant equal moles of analyte adjusted for stoichiometry. It applies the formula Ca = (Cb × Vb × a) ÷ (Va × b) and shows the working so you can check each step by hand.
Is the Titration Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
