Convert between pH, pOH, hydrogen ion concentration, and hydroxide ion concentration using the relationship pH + pOH = 14 at 25°C.

METHOD / LOCAL RUN
pH = -log10([H⁺]). pOH = 14 − pH. [H⁺] = 10^(-pH). [OH⁻] = 10^(-pOH).
Boundary: Valid for dilute aqueous solutions at 25°C. Not for strong acid/base concentrations or non-aqueous systems.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. The pH calculator runs entirely locally.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: Mode, pH or [H⁺] (mol/L) are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Valid for dilute aqueous solutions at 25°C. Not for strong acid/base concentrations or non-aqueous systems.
