Webb8 juni 2015 · A change in concentration/activity of H 3 O + is a change in pH because pH is the negative log10 of this concentration/activity. Thus, with changes in temperature, the pH of any solution will change. In fact, at -35 C° the pH of pure distilled water is measured as 8.5. At 0 C°, the neutral pH is 7.5. For every 1 degree increase, the neutral ...
