SUMMARYMeasurement of the effect of KC1 addition to a soil suspension in pH‐stat experiments indicates that the pH titration curves of such a multicomponent system are characterized by a Curve of Zero Salt Effect (CZSE) rather than a Point of Zero Salt Effect (PZSE). This curve is most accurately measured as a functional relation between pH and KC1 molarity. The described method is very accurate and, by its rapidity, precludes long‐term changes in the sample which are the bane of classic batch experiments. In analogy, multicomponent soil systems will probably be characterized by a Curve rather than a Point of Zero Net Charge (PZ
