How Does Temperature Affect pH? - Westlab Posted on the 29th of Nov 2016 by 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: Does the storage temperature affect the acidity of orange ju Does the storage temperature affect the acidity of orange juice?
