Abstract

Published data of pH and conductivity in some acid humic waters have shown erroneous corresponding values. This means that the values were not consistent with each other according to well-recognized hydrochemistry. A main questions was arised in this connection. Were the measurements correct and if not which of them were wrong, pH, conductivity or both ? Assessment on basis of calculated and measured conductivity values, by using published data and own measurements, indicate primarily erroneous pH measurements. This makes the scientific papers which are based on these remarkable results partly of questionable value. Conductivity should generally act as a controlling parameter even if the latter also could have some uncertainties.
