A pH of 7 (pure water) is neutral a pH higher than 7 is basic (alkaline) and less than 7 is acidic. pH is measured on a logarithmic scale. This means that each 1.0 change in pH (positive or negative) is a difference of a factor of 10. Thus a pH of 8.0 is 10 times more basic than 7.0 and 100 times more basic than 6.0. The average pH for sea

How Does Temperature Affect pH Westlab
Temperature plays a significant role in pH measurements. As the temperature rises molecular vibrations increase which results in the ability of water to ionise and form more hydrogen ions. As a result the pH will drop. The dissociation of water into hydrogen and hydroxide ion can be represented as H2O (l) ⇌ H (aq)

Why does pH change with temperature Chemistry Stack
The pH is the negative decadic logarithm of the H X 3 O X concentration (pH =log (c (H X 3 O X )). As chemical equilibria might change with temperature so does the concentration of H X 3 O X and therefore the pH. Although I never tried I suppose this could affect measurements using pH paper.

How Does Temperature Affect pH Westlab
The pH value of a solution is directly dependent on the temperature. A pH value without a temperature value is incoherent. Solution temperature compensation (STC) converts measured pH to the pH at 25°C. pH values taken at the same temperature or converted using solution temperature compensation can be compared to each other.
