A no-nonsense naoh dilution calculator built for solution preparation. It shows the substituted formula, not just the answer, so you can check the working.

About NaOH Dilution Calculator

Dilute a NaOH stock to a working molarity for titration and pH adjustment. The calculation uses Cโ‚Vโ‚ = Cโ‚‚Vโ‚‚. The stakes: Getting a concentration right is the difference between a reaction that works and one that quietly fails. Weigh-out and dilution errors are among the most common โ€” and most costly โ€” mistakes at the bench. Watch out for: diluting concentrated acid by adding water to acid instead of acid to water; not bringing the solution to its final volume in a volumetric flask; forgetting to account for hydrate water in the molar mass. Because the calculation happens entirely client-side, you can use it offline and with confidential data, then cite the stable URL in your methods or teaching notes.

Frequently asked questions

Is this naoh dilution calculator free to use?+

Yes. It is completely free, needs no sign-up, and runs entirely in your browser โ€” there are no usage limits.

What formula does it use?+

It uses Cโ‚Vโ‚ = Cโ‚‚Vโ‚‚ The full worked example is shown beneath the result so you can verify each step.

What are the most common mistakes here?+

In solution preparation, watch for: forgetting to account for hydrate water in the molar mass; confusing % w/v with % w/w; diluting concentrated acid by adding water to acid instead of acid to water; not bringing the solution to its final volume in a volumetric flask. This tool shows the working so you can catch these before they cost an experiment.

Does my data leave my device?+

No. All computation happens locally in your browser. Nothing you enter โ€” sequences, concentrations or measurements โ€” is uploaded to any server, so it is safe for confidential work.

Can I cite this tool?+

Yes โ€” use the โ€œCite this toolโ€ snippet on the page. Many users link these calculators from methods sections, lab SOPs and teaching materials.
