Neutral pH Point Calculation

It is common knowledge that pH 7 is the neutral point, at which H+ and OH ions equal. However, it is not that simple. Firstly, this is only true at 25 °C, and secondly, it is not exactly 7. The self-dissociation of water, and with it the neutral point, are strongly temperature dependent. This calculator allows to calculate the neutral point for any temperature between 0 °C and 60 °C.
This pH temperature dependence must not be confused with the temperature dependence of electrodes, which is compensated in most commercial electrodes – this does NOT correct the effect of changes in the self-dissociation of water!

Please enter the temperature in °C:
