Figure 5 Theoretical Conductivity as a Function of pH
Figure 5 shows the theoretical relationship of pH versus conductivity in a solution containing
pure water. A second curve is added to the graph that illustrates the relationship that exists
when nitric acid (HNO ) is used as a pH control agent (such as may be utilized in facilities with
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 facilities
using cation resins of a different base such as lithium or barium.
