2013, Developments in Clay ScienceCitation Excerpt :The pH must not decrease below 4.5; control with a glass electrode is not always reliable because the electrode often does not indicate correct pH values in the presence of clays. Indicator strips are more reliable (Keller and Matlack, 1990). Recommended is an acetate buffer solution of pH = 4.8 (2 M sodium acetate + 2 M acetic acid) instead of hydrochloric acid.
