Step 1 • Add values

Use the calculator

Enter your values below to generate an instant result. You can update the inputs at any time to compare different scenarios.

Example: 50.00 mL HCl titrated with 35.23 mL of 0.250 mol/L NaOH gives 0.17615 mol/L HCl.

HCl concentration at equivalence

0.17615 mol/L1:1 HCl and NaOH titration

HCl concentration at equivalence: 0.17615 mol/L (1:1 HCl and NaOH titration)

At the equivalence point, moles of HCl equal moles of NaOH. Divide titrant molarity multiplied by its titre volume by the HCl sample volume.

One-to-one neutralisation

At the equivalence point, moles of HCl equal moles of NaOH. Divide titrant molarity multiplied by its titre volume by the HCl sample volume.

Recommended next checks

  • →Confirm the NaOH concentration and measured titre from your experiment.
  • →Use the balanced reaction and a different method for any other analyte or titrant.

Applies only to a 1:1 aqueous HCl/NaOH reaction when the measured endpoint represents equivalence. It does not calculate pH, account for endpoint error, or validate laboratory safety.

Try different values to compare results.

Use a known NaOH concentration and the measured NaOH titre to calculate the molarity of an HCl sample. The calculation assumes the endpoint represents the 1:1 equivalence point.

About Titration Calculator

Titration Calculator helps you work through the main numbers for this topic quickly with a simple input flow and an instant result.

Use the calculator result as a practical starting point, then review the explanation and assumptions on the page if you want more context.

HCl and NaOH titration formula

HCl + NaOH reacts in a 1:1 mole ratio. At equivalence, HCl molarity = NaOH molarity x NaOH titre (mL) / HCl sample volume (mL). The common mL units cancel. For a 50.00 mL sample and 35.23 mL of 0.250 mol/L NaOH, the result is 0.17615 mol/L HCl.

This result is sample concentration, not solution pH. Other analytes, titrants, reaction coefficients and endpoint errors require a separate method. Follow laboratory safety procedures when handling acids and alkalis.

FAQ

Common questions

No. It supports only HCl titrated by NaOH at a 1:1 equivalence point with a known NaOH concentration.

Trust and notes

Assumptions and important notes

This calculator is designed to give a fast estimate using the method shown on the page. Results are most useful when your inputs are accurate and the tool matches your situation.

Use the result as guidance rather than a final diagnosis or professional decision. If the result could affect health, legal, financial, or compliance decisions, verify it with a qualified source where appropriate.
