WebIn general one has to assume that a temperature change results in a pH change (see buffer/temperature table). The reason for this is the temperature dependent dissociation which causes a change in the H+concentration. This pH change is real, not a measuring error, and cannot be compensated for by use of ATC. WebThe neutral value of the pH depends on the temperature and is lower than 7 if the temperature increases above 25 °C. ...
