About Henderson–Hasselbalch Calculator — Borate
Find the pH of a Borate buffer from the molar ratio of conjugate base to acid using the Henderson–Hasselbalch equation. The calculation uses pH = pKa + log([A⁻]/[HA]). Why this calculation counts: A buffer that drifts even half a pH unit can denature an enzyme, ruin a crystallization, or shift a binding assay. Buffer choice and accurate pH are foundational to reproducible biology. Common pitfalls to avoid: ignoring the temperature dependence of Tris; adjusting pH at the wrong temperature; exceeding the useful buffering range (pKa ± 1). All maths runs locally in your browser; no data is ever sent to a server. That privacy is exactly why researchers link these calculators from protocols, theses and standard operating procedures.

Frequently asked questions
Is this henderson–hasselbalch calculator — borate free to use?+
Yes. It is completely free, needs no sign-up, and runs entirely in your browser — there are no usage limits.
What formula does it use?+
It uses pH = pKa + log([A⁻]/[HA]) The full worked example is shown beneath the result so you can verify each step.
What are the most common mistakes here?+
In pH and buffer chemistry, watch for: picking a buffer whose pKa is far from the working pH; ignoring the temperature dependence of Tris; adjusting pH at the wrong temperature; exceeding the useful buffering range (pKa ± 1). This tool shows the working so you can catch these before they cost an experiment.
