WebAug 1, 2024 · ph temperature 4,796 Water always contains a certain amount of \ce O H − and \ce H 3 O + ions. The pH is the negative decadic logarithm of the \ce H 3 O + concentration (pH = - log (c ( \ce H 3 O + )). As chemical equilibria might change with temperature so does the concentration of \ce H 3 O + and therefore the pH. WebpH with temperature, as known from pH buffer solutions. That is why no exact temperature compensation can be made with sample measurements. In order to correct the pH value of a sample to the calibration temperature, the following formula is commonly used in pH meter software.
