Acids, Bases, & the pH Scale - Science Buddies
The measurement of pH can become difficult at extremely acidic or alkaline conditions, such as below pH 2.5 (ca. 0.003 mol/dm 3 acid) or above pH 10.5 (ca. 0.0003 mol/dm 3 alkaline). This is due to the breakdown of the Nernst equation in this conditions when using a glass electrode.
