CHEMISTRY PARAMETERSDOE-HDBK-1015/2-93Reactor Water ChemistryCH-03Rev. 0Page 20Figure 5 Theoretical Conductivity as a Function of pHFigure 5 shows the theoretical relationship of pH versus conductivity in a solution containingpure water. A second curve is added to the graph that illustrates the relationship that existswhen nitric acid (HNO ) is used as a pH control agent (such as may be utilized in facilities with3aluminum components). In both Figure 4 and Figure 5, a definite relationship exists between pH and conductivity,assuming no foreign ions are present. A similar graph could be constructed for those facilitiesusing cation resins of a different base such as lithium or barium.
